Gauteng police launched a manhunt for a group of gunmen following a cash-in-transit heist in Diepsloot on Friday morning at around 09:00.
According to police, a cash van crew was in Diepsloot to drop off money at several ATMs when a Mercedes-Benz fitted with false number plates rammed into it near William Nicol drive.
Police spokesperson Colonel Athlenda Mathe said the crew managed to drive on but were cornered by the same suspects on the R511 and R562.
She said an unknown number of suspects armed with rifles shot at the crew.
"They were then forced out of the van, after which the van was bombed with explosives and an undisclosed amount of money taken," Mathe added.
In addition, she said, three 9mm firearms were taken from the driver and his crew.
"It has also been established that the Benz used to ram the cash van was reported stolen in Roodepoort in June.
"The driver of the cash van and his crew have been taken to hospital and are being treated for shock," Mathe said.
