The IPCC (The Independent Police Complaints Commission). which was established in 2004 and is chaired by Dame Anne Owers, investigates the most serious complaints against the police, as well as the Serious Organised Crime Agency, Her Majesty's Revenue and Customs and the UK Border Agency.
A total of 31,771 officers were subject to a complaint during 2011/2012 and when appeals were made against the way forces handled a complaint, the IPCC found that the police had been wrong in one in three cases.
