During the four-day Easter weekend of 1977 (30 April – 1 May) a burglary took place at the Standard Bank in Krugersdorp, South Africa.
Work was done on the tunnel at night and the windows of the shop were covered with brown paper as most people would do when fitting out a new business and thus caused no suspicion.
Once inside the bank, the robbers broke a hole in the brick wall and opened the safe using an oxyacetylene torch.
The bank had turned off its trembler alarm systems due to compressors that were being used by a nearby building site.
Identikits of the robbers were drawn up by witnesses who said they saw the men on the weekend wearing blue overalls.
