Through his position, Williamson also received information about what the apartheid opposition was up to. When black anti-apartheid activist Steve Biko planned to travel to Botswana in September 1977 to meet Olof Palme and the ANC’s Oliver Tambo, Williamson passed the information along to his colleagues within the South African police. On August 18, 1977, Steve Biko was arrested at a roadblock and beaten severely during his interrogation. He died of his injuries on September 12. Biko was just one example of the anti-apartheid activists who died as a result of Craig Williamson’s actions.
