The Independent Police Conduct Authority is an independent Crown entity that considers complaints against the police and oversees their conduct. It was established by Parliament in 1989 as the Police Complaints Authority, which comprised a single person with a small number of staff who reviewed police investigations. Due to its reliance on police investigations the Police Complaints Authority was perceived as lacking independence. To help address this it appointed its first independent investigators in 2003. In 2007 a commission of inquiry into police conduct recommended enhanced powers to make the authority more independent. Later that year the Police Complaints Authority was given greater powers and was also renamed the Independent Police Conduct Authority. This is the 2011 version of a brochure that gives people advice on how to complain to the authority.
