Vlakplaas

Vlakplaas (an Afrikaans term meaning "flat farm") is a farm 20 km west of Pretoria that served as the headquarters of counterinsurgency unit C1 (later called C10) of the Security Branch of the apartheid-era South African Police. Though officially called Section C1, the unit itself also became known as Vlakplaas. Established in 1979, by 1990 it had grown from a small unit of five policemen and about fifteen askaris to a unit of nine squads.

The unit functioned as a paramilitary hit squad, capturing political opponents of the apartheid government and either "turning" (converting) or executing them. Vlakplaas farm was the site of multiple executions of political opponents of the apartheid government. The unit is known to have carried out the murders of Griffiths Mxenge in 1981 and the so-called "Chesterville Four" in 1986, among many others. C1 officers were also notorious for allegedly routinely defrauding the state, siphoning off government funds to pay agents or for their personal use.
