Twelve men arrested for gang-raping a woman near Driefontein Number Five shaft in Carletonville will appear in court next week, police said on Friday.

Lt-Col Lungelo Dlamini said they would be charged in the Carletonville Magistrate's Court on Monday.

The men were arrested on Thursday morning.

"It is alleged that the victim and her friend were on their way home to Mpahla Village in Carletonville on Wednesday when they were confronted by illegal miners," Dlamini said.

The woman (23) was hit on the head with a knobkerrie before being dragged to nearby bushes where she was raped by eight men. Her friend escaped unharmed.

Dlamini said the men then took the woman to a shack where another four men joined in raping her.

"She sustained multiple injuries on the head, face and body, and was taken to hospital," he said.

He said the arrested men were from Lesotho and three were still being sought.
