The South African police arrived on the crash site four and a half hours after the crash. It was alleged that they initially ignored the dead and wounded people and started collecting the documents papers scattered around the scene as well as the victims' valuable personal items and cash. Foreign Minister, Pik Botha, Niel Barnard, head of the National Intelligence Service, who arrived later, admitted that the documents had been removed from the scene for copying.
