A plain-language overview from Amicus International explaining how a domestic criminal case becomes an international police alert, how authorities detect a wanted person across borders, and what occurs during identity confirmation, provisional arrest, and the urgent transition toward formal extradition proceedings.
WASHINGTON, DC, September 9, 2026 — An INTERPOL Red Notice can travel through international police systems within moments, but the legal process behind that alert usually begins much earlier with a domestic investigation, a valid national warrant, and a government decision that the wanted person may be located abroad.
The notice asks law-enforcement authorities worldwide to locate and provisionally arrest an identified person pending extradition, surrender, or comparable legal action, although it remains an international cooperation request rather than a universal arrest warrant commanding identical action in every country.
In practical terms, a Red Notice connects a requesting country’s criminal process with the police, border, immigration, and judicial systems of other countries, creating a structured way to locate someone whose whereabouts are unknown or whose international movements might otherwise escape domestic authorities.
That connection can produce dramatic results at an airport or border crossing, yet every arrest still depends on the law of the country where the person is encountered, because INTERPOL neither sends arresting officers nor claims authority over national courts.
This public guide from Amicus International follows the operational sequence from the original warrant through INTERPOL screening, international circulation, database matching, identity verification, provisional custody, and the urgent document exchange that determines whether detention can continue.
Stage One: A Domestic Criminal Case Produces a Warrant
The practical Red Notice process normally starts when authorities investigating a serious ordinary-law crime obtain an arrest warrant, detention order, sentence-enforcement order, or comparable judicial decision that remains legally valid within the requesting country.
The person may be accused and wanted for prosecution, in which case the presumption of innocence continues, or may have been convicted and sought to serve a sentence, a distinction that must be accurately reflected within the international request.
Investigators usually gather biographical and operational information before seeking international circulation, including full names, aliases, citizenship, birth details, passport numbers, photographs, fingerprints, suspected locations, travel patterns, offense descriptions, warrant information, and the potentially applicable legal penalty.
The requesting authority must also determine whether it genuinely intends to pursue extradition if another country locates the person, because a Red Notice is not designed merely to monitor an individual indefinitely without action toward lawful surrender.
Police and prosecutors may examine relevant extradition treaties, dual-criminality requirements, evidentiary standards, limitation periods, nationality restrictions, likely punishment concerns, and document requirements before circulating the case, since those issues can determine whether another government will act.
A weakly prepared request can fail during INTERPOL review, produce hesitation among foreign authorities, or collapse after provisional arrest when the requesting country cannot deliver authenticated evidence and legal documents within the applicable treaty deadline.
Stage Two: The National Central Bureau Prepares the Request
Every INTERPOL member country maintains a National Central Bureau, commonly called an NCB, which serves as the official connection between domestic law-enforcement agencies, other member countries, and INTERPOL’s General Secretariat in Lyon, France.
The investigating agency typically forwards the case to its NCB, which reviews the submission, confirms the underlying warrant, organizes identification data, summarizes the alleged conduct, and transmits a formal request for Red Notice publication through secure channels.
The request must identify the offense with enough factual clarity to show serious ordinary criminal conduct rather than relying exclusively upon a statutory label, political accusation, private commercial dispute, family disagreement, administrative violation, or culturally controversial prohibition.
It must also establish that the person is sufficiently identifiable, because an alert containing vague names, uncertain birth information, or inadequate supporting details could cause false matches while failing to help police distinguish the actual subject from innocent travelers.
At this stage, the requesting country remains the source and owner of the case information, while INTERPOL provides the international processing framework rather than independently investigating the alleged crime or rewriting the underlying accusation.
Stage Three: INTERPOL Screens the Submission
INTERPOL’s Notices and Diffusions Task Force reviews incoming Red Notice requests before authorization, using legal, operational, and data-quality expertise to determine whether proposed circulation complies with the organization’s Constitution and Rules on the Processing of Data.
Reviewers examine whether an enforceable warrant or equivalent judicial order exists, whether the offense meets seriousness requirements, whether the request provides sufficient identification details, and whether the requested international processing serves a legitimate law-enforcement purpose.
They also assess compliance with Article 2, which links international police cooperation to national law and the Universal Declaration of Human Rights, and Article 3, which prohibits interventions or activities with a political, military, religious, or racial character.
The review may consider the subject’s political position, refugee status, public reporting, previous extradition decisions, the broader dispute, information from other National Central Bureaus, and whether ordinary criminal allegations genuinely predominate over prohibited political features.
When questions arise, the task force can request more judicial information, seek clarification from the submitting NCB, examine material from other countries, restrict visibility during review, or deny the proposed notice when required conditions remain unsatisfied.
If the submission complies, the General Secretariat authorizes publication and notifies National Central Bureaus throughout the member network, but authorization confirms institutional compliance rather than guilt, evidentiary truth, or the legality of arrest under every country’s domestic law.
Stage Four: The Red Notice Enters Police Systems
Once published, the Red Notice becomes available through INTERPOL’s secure systems to authorized authorities, while member countries decide how its identifying and judicial information will interact with national police databases, border controls, immigration platforms, and fugitive-tracking procedures.
The notice generally presents two categories of information, combining identity data such as names, aliases, photographs, fingerprints, nationality, and document details with judicial data describing the alleged offense, warrant, legal provisions, and sentencing exposure.
Some extracts appear on INTERPOL’s public website when public assistance could help locate the person, although many notices remain restricted to law enforcement, meaning absence from an open internet search cannot reliably establish that no international circulation exists.
Police may also receive location intelligence through bilateral cooperation, passenger information, criminal investigations, visa processing, residence applications, financial inquiries, or tips, allowing an NCB to focus attention on a particular country even when the original location was unknown.
The practical value of circulation comes from placing the same structured alert before multiple countries simultaneously, reducing dependence upon slow bilateral inquiries and giving border authorities an opportunity to identify the subject during otherwise routine processing.
Stage Five: A Database or Officer Produces a Match
A potential match may appear when immigration officers scan a passport, airline passenger information reaches an authorized screening system, police check identification during an unrelated encounter, or investigators compare a photograph, fingerprint, alias, telephone record, or address against wanted-person data.
In March 2026, Indonesian authorities said immigration officers detained a Scottish man shortly after his arrival at Bali’s international airport when their system flagged a Spanish Red Notice, illustrating the border-detection process described in The Associated Press report.
The operational speed of such encounters can make the Red Notice appear self-executing, although officers must still identify a domestic legal power permitting their response and should not assume that a computer match conclusively establishes identity or arrest authority.
A match may initially prompt discreet observation, secondary inspection, questioning, document examination, consultation with an NCB, or temporary movement restrictions while authorities verify the record and determine whether applicable national law permits provisional arrest.
The encountered person may learn about the notice for the first time during that process, because advance notification is not guaranteed and public Red Notice listings represent only a portion of the information available to law enforcement.
Stage Six: Authorities Confirm the Person’s Identity
Identity confirmation is a critical safeguard because common names, inconsistent transliterations, estimated birth dates, outdated photographs, similar appearances, stolen passports, and incorrect biographical data can create dangerous false matches across large international databases.
Officers may compare facial images, fingerprints, signatures, physical features, citizenship history, passport records, aliases, previous addresses, travel movements, and other authorized identifiers before concluding that the encountered person is the actual Red Notice subject.
The local NCB can communicate with the requesting NCB to confirm whether the alert remains active, whether the underlying warrant is valid, whether extradition will be pursued, and whether additional evidence supports the proposed identity match.
If significant discrepancies appear, responsible authorities should resolve them before imposing prolonged custody, because wrongful detention can generate severe personal, financial, immigration, medical, and reputational consequences while undermining public trust in international police cooperation.
Accurate identification does not establish guilt, however, since it demonstrates only that the person encountered appears to match the individual described by the requesting country, leaving the allegations for appropriate courts to assess under applicable law.
Stage Seven: Local Law Determines the Immediate Response
After confirming a probable match, authorities determine what legal value their country assigns to the Red Notice, which can range from immediate provisional-arrest authority to a requirement for additional diplomatic papers, prosecutorial approval, or a locally issued judicial warrant.
Some countries permit police to arrest on the strength of a compliant Red Notice and then bring the person promptly before a judge, while others require a separate provisional-arrest request transmitted under an extradition treaty or domestic statute.
Certain jurisdictions may initially rely upon immigration powers, passport controls, or administrative detention when those mechanisms lawfully apply, although deportation, expulsion, and extradition remain legally distinct procedures carrying different protections, standards, and consequences.
The United States does not treat a foreign Red Notice alone as sufficient arrest authority and requires an appropriate domestic judicial process, while other member countries may assign the same international alert a stronger immediate effect under their national legislation.
This variation explains why a subject can travel through one jurisdiction without detention before being arrested in another, even though both countries received identical INTERPOL information and neither necessarily disputes the validity of the underlying foreign warrant.
Stage Eight: Provisional Arrest Preserves the Extradition Opportunity
Provisional arrest is an urgent, temporary mechanism intended to prevent departure while the requesting country prepares and delivers its complete extradition request, not a final judgment that the person must be surrendered or is guilty.
The legal authority may come from a treaty, extradition statute, domestic warrant, or judicial order, and arresting officers should inform the person of the asserted basis for custody under local constitutional and procedural requirements.
After arrest, authorities commonly seize or secure travel documents, record property, conduct approved identification procedures, notify prosecutors and the relevant NCB, arrange necessary interpretation, and bring the person before a competent judicial authority within the legally required period.
The person may have rights to counsel, interpretation, medical treatment, consular communication, notice of allegations, judicial review, and a bail application, although the precise protections and availability of release differ substantially among legal systems.
Courts often consider flight risk, identity, community ties, the seriousness of the allegations, treaty obligations, and the likelihood that formal documents will arrive, while some jurisdictions apply unusually demanding standards for release during extradition proceedings.
Provisional arrest should therefore be understood as the beginning of the requested country’s judicial process, not as an extension of the requesting country’s criminal trial or an administrative delivery ordered directly by INTERPOL.
Stage Nine: The Deadline Starts Running
Once provisional arrest occurs, the requesting country must usually provide a formal extradition request and supporting documents within the period specified by the applicable treaty or statute, creating immediate pressure upon investigators, prosecutors, diplomats, translators, and justice ministries.
The United States Department of Justice guidance on international extradition explains that treaty deadlines following provisional arrest commonly range from approximately thirty days to three months, depending upon the controlling agreement and requested country.
Required supporting materials may include authenticated warrants, charging instruments, factual narratives, legal provisions, limitation information, identity evidence, conviction judgments, sentencing records, and certified translations properly prepared in the official language required by the requested state.
If those materials do not arrive properly and on time, a court may release the detained person, although release for missed provisional-arrest deadlines does not necessarily erase the national warrant or prevent a later extradition request where governing law permits renewal.
The requesting government may avoid provisional arrest when flight risk appears manageable, instead completing the formal package first and asking the requested country to issue an arrest order after all necessary extradition documents are available.
That slower document-first approach substantially reduces deadline pressure and translation risk, while the urgent provisional-arrest route prioritizes preventing imminent international movement before the complete diplomatic, judicial, and evidentiary package can reasonably be assembled.
The First Hearing Is Not the Criminal Trial
During an initial appearance, the local court generally addresses custody, identity, procedural validity, legal representation, and document deadlines rather than deciding whether the foreign accusation is ultimately true beyond the standard required for conviction.
The requesting country’s criminal court remains responsible for the underlying prosecution or sentence, while the requested country’s independent judiciary determines whether continued detention and possible extradition satisfy its treaty, statutory, constitutional, procedural, and human-rights obligations.
A contested extradition case can later examine dual criminality, treaty coverage, evidentiary sufficiency, political-offense restrictions, limitation periods, prior adjudication, nationality protections, prison conditions, fair-trial concerns, diplomatic assurances, and documented risks involving torture, persecution, or capital punishment.
Those later issues explain how provisional arrest can be valid even when extradition is eventually refused, because temporary custody and final surrender answer different legal questions at different stages of the international process.
What INTERPOL Does During and After an Arrest
INTERPOL facilitates information exchange among National Central Bureaus and maintains the international record, but local police conduct the arrest, local courts supervise detention, and the requesting and requested governments handle the formal extradition process.
The organization may update, restrict, or delete information when circumstances change, particularly if the requesting NCB withdraws the request, the warrant expires, compliance concerns emerge, or the Commission for the Control of INTERPOL’s Files orders corrective action.
When INTERPOL deletes a Red Notice, it removes the alert from its systems and informs member countries, although national authorities may retain independent records based upon domestic warrants, bilateral messages, immigration decisions, or earlier investigations.
For that important reason, deletion does not automatically invalidate the requesting country’s underlying warrant, terminate an extradition case already supported through independent diplomatic channels, or instantly clear every national database that previously received or copied related information.
Errors, Challenges, and Requests for Deletion
A person who believes a notice contains mistaken identity data, outdated judicial information, politically motivated allegations, private-dispute material, or other noncompliant content may seek access, correction, or deletion through the Commission for the Control of INTERPOL’s Files.
The Commission examines compliance with INTERPOL’s governing rules rather than conducting the foreign criminal trial, meaning applicants should present focused evidence about data accuracy, political context, refugee status, warrant validity, extradition intentions, and relevant human-rights concerns.
Counsel may also need to challenge provisional detention locally, address the originating criminal case, coordinate immigration or asylum protection, and communicate with authorities holding copied records, because a Commission application resolves only the INTERPOL data component.
Allegations of historical misuse involving political opponents, dissidents, refugees, and business adversaries reinforce the need for independent review, but a challenge should rely on documented facts rather than assuming every internationally circulated prosecution is illegitimate.
What Families Should Do After Provisional Arrest
Families should immediately record the detention location, arresting agency, officers’ names, case number, alleged legal authority, next hearing, and any transfer destination, while avoiding public speculation that could complicate coordinated legal submissions across jurisdictions.
They should provide counsel with accurate identity documents, medical needs, immigration history, prior court materials, refugee or protected-status decisions, contact information for foreign lawyers, and records showing withdrawn warrants, previous extradition refusals, or known database errors.
Qualified local extradition counsel should communicate with a lawyer in the requesting country, because the first team addresses custody and surrender while the second verifies the warrant, charges, evidence, procedural history, and available remedies within the originating case.
The Amicus International resource on Red Notices and extradition provides additional context for early risk assessment, coordinated international review, and lawful response planning when cross-border police circulation produces detention, immigration, travel, or reputational consequences.
The Practical Sequence in One View
In practical terms, the requesting country obtains a warrant, its National Central Bureau assembles the case, INTERPOL screens the submission, the General Secretariat circulates an approved notice, and foreign systems can recognize the wanted person.
A border officer, investigator, or authorized database then identifies a possible match, local authorities verify identity and notice status, domestic law determines whether arrest is permitted, and provisional custody preserves time for the formal extradition package.
Nothing within that sequence makes the Red Notice a conviction or universal warrant, because the requesting state owns the allegation, INTERPOL operates the cooperation channel, and the country of arrest supplies the legal authority controlling custody.
The process can move from database match to detention within hours, yet continued custody depends upon deadlines, documentation, judicial oversight, and national protections that prevent an international alert from becoming an automatic order of surrender.
This guide provides general public information, not legal advice, and anyone facing an INTERPOL alert, border stop, provisional arrest, immigration action, or extradition request should seek qualified counsel immediately because each jurisdiction has different procedures and deadlines.
