The Independent Police Complaints Commission is 'woefully underequipped', according to a group of MPs, who says it relies too heavily on former officers and police resources.
Keith Vaz, the chair of the Home Affairs Select Committee behind the report, said that he felt that the IPCC needs to take quicker action, once a crime has happened.
Speaking to ITV Daybreak, he said: "When you make a complaint about the police you want to feel that someone independently is dealing with the case, not the police investigating themselves."
