Institution type

Independent police investigative body

An external body whose statutory job is to investigate suspected CRIMES by police officers. Some also handle conduct complaints; two of the clearest examples handle none at all, and must turn away a report that discloses no offence.

Fact-checkedLast updated Last reviewed

Why this kind of body exists

When a police officer is suspected of a crime, the ordinary answer — the police investigate it — puts a force in charge of building a case against its own. These bodies exist to move that specific decision outside the force. The question they are built for is narrow and criminal: was an offence committed. That narrowness is the design, not a gap in it.

What distinguishes it

  • The trigger is a criminal allegation or a mandatory referral, not a complaint about conduct
  • Investigative powers are police-type powers — search, seizure, compelling evidence — held under criminal procedure
  • What happens at the end is a prosecution decision, taken by the body itself or by a prosecutor it must refer to

Typical mandate

  • Investigating suspected criminal offences committed by police officers, usually in the course of duty
  • Investigating deaths and serious injuries caused by police action or occurring in custody, whether or not an offence is suspected
  • Referring the file to a prosecutor, or in a minority of systems deciding the prosecution question directly

How authority reaches it

The arrangements differ so much that the only safe generalisation is that each rests on a statute. Norway’s body is constituted by chapter 34 of the prosecution instruction as a nationwide investigating and prosecuting authority whose staff may not simultaneously be employed in the police or the prosecuting authority. Czechia’s is an armed security force in its own right, whose director is appointed and removed by the prime minister and whose budget is a separate chapter of the state budget. South Africa’s functions independently from the police service under section 4(1) of its Act, while its Executive Director is nominated by the Minister, confirmed by a parliamentary committee, and removable by the Minister — a statement of independence with a stated scope.

Commonly confused with

  • That this is the same thing as a police complaints body. Some systems combine them; Norway and Czechia do not, and both are required to turn away matters that disclose no criminal offence.
  • That such a body can discipline the officers it investigates. None of the bodies researched for this page can. Discipline runs through the police hierarchy, sometimes under a statutory duty to act on a recommendation.
  • That investigating crime implies prosecuting it. One of the bodies here prosecutes; the rest must refer to a prosecution service, which takes the charging decision itself.
  • That the remit is always police-only. Czechia’s body covers the police, the customs administration and the prison service alike.

Where it exists

Present in a minority of systems, and by no means the default. Where no such body exists the investigation of a suspected offence by an officer may fall to another police force, to a specialised unit inside the same force, to a prosecutor, or to an investigating judge. Sweden is the clearest case of the alternative: the investigating department sits inside the police authority and a prosecutor outside it directs every case.

Historical background

Several of these bodies replaced an arrangement judged too close to the police. Czechia’s inspection replaced the Inspectorate of the Police of the Czech Republic, which sat in the Interior Ministry, and the 2011 Act moved the whole staff and budget across. Naming a predecessor as though it were current is the recurring error with this family, because the replacements are recent and the names are similar.

What examines it

Independence here is bounded in ways the word does not convey, and the bounds are usually in the same instrument that grants it. Norway’s Director of Public Prosecutions may order the bureau to open an investigation, to carry it out, and to stop it. Kenya’s Authority may not investigate a matter that is before a court. South Africa’s Act states independence from the Service and is silent about the Minister who appoints and may remove its head. Reading any of these bodies as unconstrained misdescribes them.

Worked examples

Systems this platform has researched. Each example shows how one country actually arranges this — including where it departs from the general pattern.

Norway
Spesialenheten for politisaker is the purest case, and the one that shows the family is not a complaints body. Chapter 34 of the prosecution instruction makes it a nationwide investigating AND prosecuting authority for criminal acts committed in the course of duty by police or prosecution employees — and requires its chief to reject a report that falls outside that, expressly including one where the reported matter is not criminal. It must investigate a death or serious injury caused by police duty even with no suspicion of an offence, and where a case suggests an administrative response it sends it to the officer’s own commander rather than acting itself.
Czechia
The General Inspection of Security Forces is the case that breaks the police-only assumption twice over. It investigates crimes by officers of the police, the customs administration and the prison service; and it is itself an armed security force under section 1(1) of Act No. 341/2011, with powers to detain and to use coercive means. Its Act contains no complaint procedure: a member of the public may alert it to conduct by another force’s officer only where that conduct amounts to a criminal offence. It does not prosecute — the state prosecutor decides that, and offences by the inspection’s own members are investigated by the state prosecutor rather than by itself.
South Africa
The Independent Police Investigative Directorate shows the bounded-list model. Section 28(1) of Act 1 of 2011 requires it to investigate deaths in custody, deaths from police action, discharge of an official firearm, rape by an officer or of a person in custody, torture or assault in the execution of duty, and corruption within the police — and section 35(6)(b) sends ordinary service complaints to the police service instead. Its remit covers municipal police services as well as the national one. It must refer criminal offences to the National Prosecuting Authority, and on a disciplinary recommendation the Commissioner must begin proceedings within 30 days: a duty on the police to act, not a power in the Directorate to decide.
Denmark
Den Uafhængige Politiklagemyndighed holds both mandates at once, which is why the two families on this site overlap rather than divide. It handles conduct complaint cases and investigates criminal cases against police and prosecution personnel, and it opens an investigation where a person dies or is seriously injured in a police intervention or in custody. Its governing council is chaired by a High Court judge and it states independence of both the police and the prosecution service.
Ireland
Fiosrú, the Office of the Police Ombudsman, is the other combined body. Under Part 6 of the Policing, Security and Community Safety Act 2024 it takes public complaints and also investigates, with powers equivalent to a member of An Garda Síochána and a power to search Garda premises, referring to the Director of Public Prosecutions under section 214. It is not the destination for every complaint: sections 200 to 202 route defined categories back to An Garda Síochána for resolution.
Kenya
The Independent Policing Oversight Authority reaches furthest of any body here, and still does not prosecute or discipline. It investigates disciplinary and criminal offences alike, inspects police premises including detention facilities, audits the Service’s own Internal Affairs Unit, and may take over an internal investigation that is inordinately delayed or manifestly unreasonable. Prosecution is recommended to the Director of Public Prosecutions, whom it may require to respond.

Where the pattern does not hold

Countries with government at the same level that do not own this function. The pattern above is a pattern, not a rule.

Sweden
Sweden has no body of this type and investigates police crime anyway. The Department for Special Investigations is, in the police authority’s own words, "en oberoende avdelning inom Polismyndigheten, avskild från övrig polisverksamhet" — an independent department inside the Police Authority, separated from other police activity — and a prosecutor at the Särskilda åklagarkammaren always leads the preliminary investigation. The function is split between a ring-fenced department inside the police and a chamber inside the prosecution service. Sweden shows that a dedicated external body is one design for this problem, not the definition of solving it.
France
France places the criminal-investigation power inside the forces. The Inspection générale de la Police nationale is a service of the police’s own director general and opens judicial investigations on its own initiative, while the external Défenseur des droits may recommend, enjoin and refer but cannot investigate a crime or impose a sanction. Where this page’s bodies are external and criminal, France’s are internal and criminal, and external and neither.
New Zealand
The Independent Police Conduct Authority is external, statutory and police-specific, and is still not a body of this type. Section 27 of its Act denies it the power to lay criminal charges. It investigates incidents causing death or serious bodily harm and may recommend criminal proceedings, but the criminal decision is not its to take — which is the line this page is drawn along.

Where this connects

Roles: Patrol officer.

Institutions: Police complaints body, Prosecution service, Ombuds and rights institutions.

    The consolidated Norwegian prosecution instruction, chapter 34, in the version in force from 15 August 2025, read in full. Supports: that investigation of criminal acts committed in the course of duty by an employee of the police or the prosecuting authority is carried out and led by a separate central body, Spesialenheten for politisaker, which is a "riksdekkende etterforskings- og påtalemyndighet" (§ 34-1); that persons in the unit may not simultaneously be employed in the police or prosecuting authority, with a two-year quarantine for those appointed to office, and that the Ministry of Justice holds overall administrative responsibility (§ 34-1); that the Chief decides the prosecution question except where it belongs to the riksadvokaten, and conducts the case in court where the unit indicts (§ 34-3); that the Chief MUST reject cases outside the unit’s competence, "for eksempel fordi det anmeldte forhold ikke er straffbart" (§ 34-5); that investigation shall be opened even without suspicion of an offence where a person dies or is seriously injured as a result of police or prosecuting-authority duty or while in their care (§ 34-6); that the Chief shall send a case to the relevant politimester where it should be assessed administratively (§ 34-7); and that the riksadvokaten may order the unit to open, carry out and stop an investigation (§ 34-9). It does not establish complaint handling, discipline, or inspection, none of which the chapter provides for.

Supports that it is "a national investigation and prosecution agency" whose purpose "is to investigate cases where employees of the police or prosecuting authority are suspected of committing criminal offences in the course of duty" — an independent police-crime body outside the ordinary police and prosecution chain.

    The consolidated Czech Act on the General Inspection of Security Forces, version in force from 1 January 2026, read directly. Supports: that the inspection is established as an "ozbrojený bezpečnostní sbor" — an armed security force (§ 1(1)); that its director is appointed and removed by the prime minister on the government’s proposal after discussion in the Chamber of Deputies’ security committee, and is answerable to the prime minister (§ 1(2)); that it is an organisational unit of the state whose income and expenditure form a separate chapter of the state budget (§ 1(4)); that its task is to search out, detect and investigate facts indicating a crime by an officer of the Police of the Czech Republic, the Customs Administration or the Prison Service, by its own members, and by state employees of those bodies where the offence relates to their work (§ 2(1)-(2)); that it conducts reliability tests (§ 2(3)); that it monitors unlawful activity and proposes preventive measures and methodological recommendations (§ 2(4)-(5)); that it may restrict personal liberty and use coercive means (§§ 10-11, 23-27); and that the Act provides no complaint procedure, only a duty to accept an alert and reply within 30 days, which for officers of other forces is confined to conduct amounting to a CRIMINAL offence while for its own members it extends to administrative and disciplinary offences. It does not give the inspection any disciplinary power over the forces it investigates, and it does not give it prosecuting authority: the státní zástupce decides the prosecution question, and offences by the inspection’s own members are investigated by the státní zástupce. The transitional provisions (§§ 68-70) additionally support that the inspection took over the staff, property and unfinished proceedings of the Inspekce Policie České republiky, which sat within the Ministry of the Interior — establishing the predecessor relationship.

    United Nations Office on Drugs and Crime (Education for Justice) · International organisation · link verified 2026-08-10

    The UNODC teaching module on police accountability mechanisms, read directly. Supports UNODC's own conceptual framework of accountability 'before, during and after the act' (ex-ante, ongoing and ex-post oversight); that internal control within the police service is the first degree of control in any police accountability system and works both preventively and reactively; that legal provisions alone are often insufficient for the day-to-day exercise of police powers, so services need comprehensive professional standards and codes of conduct giving practical guidance — the module's own worked example is guidance on arrest and detention procedures; and that because officers hold wide discretion and meet ethical dilemmas (the module instances bending laws for perceived greater law-enforcement objectives, and deceptive interrogation tactics used to extract a confession) services also need a code of ethics built on impartiality, fairness, equality, justice and honesty. Describes how accountability systems are DESIGNED. It does not establish that any particular system works, and no effectiveness or public-trust claim on this platform rests on it.
