When we receive a complaint, we may carry out our own investigation, refer the complaint to the Police for investigation or coordinate resolution of the complaint.
In some cases, we'll talk to you and the Police about the best way to resolve your complaint. We stay involved until your case is closed.
When a complaint is referred to the Police for investigation, we take steps to ensure the investigation is properly undertaken. This normally means actively overseeing and reviewing it when it's completed.
Police must also inform us of any incident in which Police staff, acting in the execution of their duty, cause death or serious injury.
