Stephen Bantu Biko, an anti-apartheid activist in South Africa in the 1960s and 1970s, was arrested on 18 August 1977, and interrogated by officers of the Port Elizabeth security police. This interrogation lasted 22 hours and included torture and beatings resulting in a coma. He suffered a major head injury, and was chained to a window grille for a day. On 11 September, police loaded him in the back of a Land Rover, naked and restrained, and began the 1100km drive to Pretoria to take him to a prison with hospital facilities. He died shortly after arrival at the Pretoria prison, on 12 September.
