Correctional Services said that “matters are under control” at Johannesburg’s Sun City Prison on Wed.
The mothers of two boys who drowned in Soweto at the weekend believe they were killed before their bodies were dumped in the river.
Tebogo Nxumalo, 7, and his cousin Bafana Nxumalo, 4, were found dead in Kliprivier, Soweto yesterday.
Tintswalo Vukeya, Tebogo's mother, discovered the boys' bodies in the river near Mzimhlophe hostel after three days of searching with relatives.
"The river where they were found is far from where we stay. I don't believe that a four-year-old child could have walked that distance," said Vukeya.
Bafana's mother Queen Rikhotso said the killings had devastated both families.
"What about their fathers are brothers. You can imagine the grief it has brought to the family," said Rikhotso.
The two women said they believed the boys were abducted from home by someone they knew and trusted.
"Our children were killed somewhere and dumped in the river so that it would look like they drowned," said Rikhotso.
The boys were found with their clothes on.
Vukeya said Bafana's face had a scar but she was too traumatised to investigate further.
Police spokesman Thembi Nkwashu said police could not stop people from making allegations.
"According to our investigations, there is no suspicion of foul play.
"But we 're waiting for the postmortem results," she said.
Rikhotso said she could not believe that her only son was dead.
"I feel empty without him and I
just wanted to kill myself when I heard the news."
