OR Tambo International Airport on Wednesday revealed how an estimated R24 million was stolen from a container at the airport.
A bakkie pulled up in front of a restricted access gate at 19:23 on Tuesday, according to a statement from the airport.
A white Ford Focus followed the bakkie. Both had sirens on and blue lights flashing. The occupants were several armed men, some of them wearing SAPS uniforms.
“When requested to validate their credentials, the men produced firearms, rounded up security staff in the security checkpoint and ordered them to lie on the floor,” the airport said.
The robbers went to the airside of the airport and took an undisclosed amount of money from a sealed container. No shots were fired and nobody was hurt.
Sources who did not want to be named told News24 on Wednesday that R24 million in foreign currency was removed. The money was destined for the United Kingdom.
