The incident occurred in the early hours of yesterday.
A report by Police Captain Tintswalo Sibeko revealed that, 12 unknown suspects travelling in a white Kombi and silver Sedan opened fire at tavern customers and fled the scene.
Gauteng Serious and Violent Crime Investigations together with the Crime Detection Tracing Unit have launched a manhunt for the killers.
Meanwhile, the local municipality says, there is a disturbing trend of violent crimes in the area, which it links to illegal miners. It added that it has called for an intervention by the South African Defence Force.
This is the second shooting to occur in Gauteng, three weeks after the first one occurred at another tavern.
