Multitalented artist Winnie Khumalo hopes her health will improve when she goes under the knife in J.
The councillor, her son and a neighbour were released pending investigations, said Brigadier Thulani Ngubane.
"The court felt that more information was required because it is a mob justice case."
Apparently the councillor, 44, her son, 19, and their 25-year-old neighbour assaulted the 17-year-old boy who allegedly attempted to rape someone in Brits.
"It is alleged that the suspects assaulted the victim by kicking him all over his body and throwing him on the ground. He was taken to the hospital where he later died."
Police were investigating, Ngubane said.
