http://news.bbc.co.uk/2/hi/americas/932897.stm Chile security chief was CIA informer Recently declassified documents in the United States show that the former head of the secret police in Chile, Manuel Contreras, was a paid informant for the US intelligence agency, the CIA. The report, comprising CIA documents requested by the US Congress, show that contact with Contreras began in 1974 - a year after the military coup that brought General Augusto Pinochet to power. A BBC correspondent in Washington, Nick Bryant, says the documents reinforce the view that the US turned a blind eye towards political repression in Chile during the Pinochet era and that the CIA was complicit in many human rights abuses. Pinochet's confidant As head of the security service, DINA, Contreras became the one of the most feared men in Chile, second only to General Pinochet. The general's iron rule was underpinned by the tactics of brutal repression that saw thousands die and thousands more flee into exile. Others disappeared or were tortured.
