Three men were arrested on Thursday for allegedly beating a woman to death they accused of practising witchcraft, Eastern Cape police said.

The trio, aged between 21 and 28, also faced a charge of arson and another of pointing of a firearm.

They went to a homstead in Bizana on Tuesday and allegedly assaulted a 60-year-old woman they accused of witchcraft, said Captain Mlungisi Matidane.

She died of her wounds. Her husband escaped.

"The same suspects later went back to the same homestead and set alight two rondavels. The 11 occupants survived with minor injuries."

The trio was arrested on Thursday morning and expected to appear in the Bizana Magistrate's Court shortly.

In a separate incident, three men accused of killing 65-year-old Nokitani Tshemesi and her three granddaughters, appeared in the Elliotdale Magistrate's Court on Thursday.

They had suspected the woman of practising witchcraft, police said. Their bodies were found in their home in Ntsingizi village on Tuesday morning. They had been stabbed to death. - Sapa
