The Independent Police Complaints Commission (IPCC) oversees the police complaints system in England and Wales and sets the standards by which the police should handle complaints.
It is independent, making its decisions entirely independently of the police and government. It is not part of the police.
Complaints about the conduct of people serving with the police can be sent to the IPCC, but the IPCC does not have the power to record complaints.
If you complain to the IPCC, it must, by law, forward the complaint back to the force involved for consideration.
The IPCC investigates the most serious complaints and allegations of misconduct against the police in England and Wales. These complaints are referred to the IPCC by police forces.
The IPCC may decide to investigate an incident using its own investigators (referred to as an independent investigation), or it can manage or supervise a police investigation.
The IPCC will only conduct independent investigations into incidents that cause the greatest level of public concern – for example, deaths in or following police custody.
The IPCC publish data for all police forces covering performance, news, reports and independent IPCC investigations.
