20 May 1987
Two bombs exploded at the Johannesburg magistrate's court. The first, a minor explosion that acted as a decoy, was followed by a second more powerful charge minutes later. Mr Andre Duvenhage, a police officer at John Vorster Square at the time, was one of the personnel who attended to the first explosion not knowing that it was a decoy. The second explosion claimed the lives of three policemen including Duvenhage and injured four others. Six bystanders were also injured. Two African National Congress (ANC) members and a supporter were granted amnesty by the Truth and Reconciliation Commission (TRC) in 1998 for the attack. The Commission received submissions testifying to the deaths of Mr Kobus Wilkens and Mr Andre Duvenhage and the injury of Mr Khutswane.
