Main Reef Road in Johannesburg had to be cordoned off to traffic on Monday morning after yet another cash-in-transit heist.
A police report of the incident said two luxury sedans forced the cash van off the road at 07:00.
The security guards were pulled from the vehicle at gunpoint. The gang then used explosives to try and get to the money, but made a getaway when they realised they had burnt their loot. The robbers left one of their cars burning on the scene, and fled in three vehicles.
Police spokesperson Colonel Brenda Muridili told News24 that no arrests had yet been made.
