29 February 1988
Archbishop Desmond Tutu, a central figure in the fight against apartheid, was arrested outside parliament while leading a protest march (one of many) against the death sentence of the 'Sharpeville Six'. Tutu was freed a few hours later.
Reginald Sefatsa, Reid Mokoena, Moses Diniso, Theresa Ramashamole, Duma Khumalo and Francis Mokhesi were convicted for the 1984 mob murder of Sharpeville deputy mayor Jacob Khuzwayo Dhlamini. There was a general outcry, because they were convicted and sentenced to death on the doctrine of common purpose. Following several stays of execution, they were finally reprieved in 1991 when negotiations between liberation movements and government led to the release of all political prisoners.
