Former Cosatu general secretary Zwelinzima Vavi and EFF leader Julius Malema are plotting to overthr.
Two acting magistrates have been arrested for their alleged involvement in an armed robbery.
The two allegedly robbed a scrap metal company in Krugersdorp of more than R100,000 on March 24, Lt-Col Katlego Mogale said.
Three men posing as police officers apparently pretended to be investigating a case at a second hand scrap dealer in Luipaardsvlei.
“They were driving a Honda Civic motor, dressed in private clothes wearing police reflective jackets and police caps,” Mogale said.
One of the men produced a police identity card.
“They initially pretended to be investigating a case, but then robbed the manager and staff members of approximately R110,000 cash, cellphones and a private firearm.”
On Wednesday, an off-duty police officer spotted the vehicle used in the robbery.
The vehicle was stopped, and its two occupants, who were found to be acting magistrates from Brits and Ga-Rankuwa, were arrested.
The vehicle was stolen in Linden last year.
Mogale said the men would appear in the Krugersdorp Magistrate’s Court on Tuesday on charges of armed robbery, possession of a hijacked vehicle and possession of unlicensed firearm and ammunition.
