6 October 1987
The South African police announced that they have uncovered and arrested members of the African National Congress (ANC) Western Cape command structure. The claim by the police came three months after the ANC met with a group of Afrikaners led by Frederik van Zyl Slabbert in Dakar, Senegal.  In July 1987, at the initiative of the Institute for a Democratic Alternative for South Africa (Idasa), a delegation of 62 people, mainly Afrikaners, met with the ANC in exile. Discussions were held on strategies for change, the creation of national unity, and the nature of post-apartheid South Africa. The talks continued in Ghana and Burkina Faso.
