Four armed men got away with three boxes of money in a cash heist in Polokwane on Monday, Limpopo police said.

The robbers attacked Coin Security guards while they were climbing into a security van after picking up money in Grobler Street around 11am, said Lt-Col Moatshe Ngoepe.

“The men with guns held them up and took three cash boxes.”

He said the robbers opened fire on the guards but no one was injured.

The men fled in a silver Audi with Gauteng number plates. Police were investigating.
