Nelson Mandela's arrest in 1962 came as a result of a tip-off from an agent of the US Central Intelligence Agency (CIA), a report says. The revelations, made in the Sunday Times newspaper, are based on an interview with ex-CIA agent Donald Rickard shortly before he died. Mandela served 27 years in jail for resisting white minority rule before being released in 1990. He was subsequently elected as South Africa's first black president. Rickard, who died earlier this year, was never formally associated with the CIA but worked as a diplomat in South Africa before retiring in the late 70s.
