MATABANE, Peter Itumeleng
A COSAS member who was killed by an explosive device detonated by named Vlakplaas operatives in a mine shaft in Kagiso, Krugersdorp, Transvaal, on 15 February 1982. He and three other COSAS members believed they were to be trained to use hand grenades, a ploy used later increasingly by security forces. Only one person survived the explosion. The perpetrators applied for amnesty.
