Correctional Services said that “matters are under control” at Johannesburg’s Sun City Prison on Wed.
The Evaton, Vaal, teacher who allegedly branded 23 pupils with a hot knife because they couldn't answer a maths question is still in hospital but not under police guard.
Sebokeng police spokesman Superintendent Nthabiseng Mazibuko said: "The teacher is still in hospital. The police did not take her to hospital. She is a suspect and not under arrest.
"Had she been taken to hospital while under arrest, we would have placed her under police guard.
"We are, however, constantly checking on her and the moment she is discharged we'll arrest her."
Two weeks ago, the female teacher from Letsema Ilima Primary School was apparently angry with Grade 2 pupils after they failed to answer a maths question and allegedly burnt them with a hot knife on their cheeks and arms.
The pupils claim that she had at times attacked them with stones, scalded them with hot tea and pricked them with needles.
Police launched a manhunt for the teacher after she disappeared when parents laid charges of assault with intent to cause grievous bodily harm.
She did not report for duty and was found six days later at a Sebokeng hospital where she had been admitted to a psychiatric ward.
