A thirteen-member family were found dead in their Dingleton home on the KwaZulu-Natal south coast amid suspicions they may have consumed a fatal herbal concoction, police said on Monday.

Superintendent Zandra Wiid said 13 bodies were found in the house around midday on Sunday.

"It is alleged that one family member who was trained as a traditional healer gave them a certain herbal medicine which is suspected to have been the cause of the deaths," Wiid said.

Found dead were a two-week-old baby, four boys aged between two and seven, a 17-year-old youth, a 21-year-old man, four women in their 30s and two 55-year-olds.
