The police in Carletonville are investigating a business robbery after an incident last Friday.

Staff at Bargain House Supermarket at East Driefontein were busy inside the shop at 12:15.

Suddenly a blue VW Polo stopped in front of the shop. Four unknown men jumped out and walked into the supermarket.

Two of them pointed firearms at the staff and customers and demanded valuables. They grabbed money and cellphones before fleeing the scene in their vehicle.

No one was injured during the incident.
