The suspects include an airport security guard who bought a Lamborghini sports car soon after the robbery and boasted about it on Facebook.
The BBC quoted unconfirmed sources claiming that the security guard was also found with huge cash in his luxury estate apartment.
You will recall that the robbery at the Johannesburg airport was carried out by a group of men in police uniform and a fake official vehicle.
The robbers operated in a manner that suggested they had prior knowledge about the movement of the money through the airport.
