We are independent of the police, government and interest groups.
We investigate the most serious and sensitive incidents and allegations involving the police in England and Wales.
Over time, our remit covering police forces has been extended to include:
- police and crime commissioners and their deputies
- the London Mayor’s Office for Policing and Crime, and his deputy
- certain specialist police forces (including the British Transport Police, the Ministry of Defence Police and the Civil Nuclear Constabulary)
- Her Majesty’s Revenue and Customs (HMRC)
- staff who carry out certain border and immigration functions who now work within the UK Border Force and the Home Office
- the National Crime Agency (NCA)
- officers carrying out certain functions at the Gangmasters and Labour Abuse Authority (GLAA)
Most complaints about the police are dealt with by the relevant police force. Each force has a separate department that oversees complaints. These are called ‘professional standards departments’ (PSDs).
By law, forces must refer certain matters to us. These include:
- certain complaints made to their force – such as those that include an allegation of serious corruption or serious assault
- indications that police officers or staff have committed misconduct – for example, any suggestion that a criminal offence has been committed or that a serious injury has been caused
- if someone had direct or indirect contact with the police when, or shortly before, they were seriously injured or died. However, forces only need to refer cases where the contact may have caused or contributed to the death or injury
We can direct forces to record incidents and then ‘call them in’. We can also consider incidents that have not been referred to us by police forces, and decide whether and how we will investigate them.
Further information about what police forces must refer to us is available in our statutory guidance.
When we receive a referral from a police force our assessment unit reviews the information they have provided. We decide whether the matter requires an investigation, and the type of investigation.
There are three different types of investigation:
- independent – we investigate the matter using our own investigators
- directed – we direct and control the investigation using police resources
- local – the police force PSD investigates, with no involvement from us
At the start of every investigation, we will outline which parts of the incident or event we will investigate. This is called our ‘terms of reference’.
Our investigators then gather evidence to establish all the circumstances of what’s happened. This may involve:
- taking witness statements
- interviewing police officers or members of police staff
- analysing footage from CCTV or cameras worn by police officers (body-worn video)
- obtaining other documents and records, such as telephone records
- reviewing policies that are relevant to what’s happened
Our investigations may also need forensic analysis and independent advice from experts.
At the end of our investigation, we produce a report that sets out:
- what happened
- what and how we investigated
- what evidence our investigators found
- our analysis of the evidence
We send the report to the police force. We also decide what should happen to those involved in the incident – for instance, they may need further training, or they may face a misconduct meeting or a gross misconduct hearing.
The police force can then provide its representations about what should happen. While we will consider those views, we will make the final decision on what happens as a result of our investigation.
It is the police force that carries out any disciplinary action. They can hold disciplinary hearings (for gross misconduct) or meetings (for misconduct).
The possible disciplinary actions that the police force can carry out include:
- written warning
- final written warning
- reduction on rank
- dismissal without notice
The force can also take non-disciplinary actions for low-level matters of misconduct or performance, such as ‘practice requiring improvement’. Supervising officers may also offer informal advice to their staff, identify any training needs and arrange for these to be met.
If our investigations find areas for improvement or learning opportunities, we can make recommendations to the force involved – or to all forces, if appropriate.
We provide a copy of our investigation report to the relevant police force and also to:
- the person who complained or was injured
- in cases involving a death, the family of the person who died
- the Crown Prosecution Service (CPS) – but only in cases where we think a police officer or member of staff may have committed a criminal offence. The CPS will then decide whether to prosecute
- the Coroner – but only in cases where someone has died. If an inquest is to be held, it will consider our evidence
