Pistorius who is serving a six-year prison sentence for murdering girlfriend Reeva Steenkamp was rushed to hospital last Saturday with slashed wrists.
Officers who searched his cell reportedly found blades, but Pistorius and his family denied he was trying to commit suicide. instead insisting he had fallen out of bed.
However, South Africa's Eyewitness News is now reporting that he is under suicide watch at the Kgosi Mampuru Prison. It also says he has filed a complaint against three nurses at the prison, saying they attempted to kill him.
He reportedly claims they gave him medication which was “toxic” and has had a request move to a different prison denied.
His legal team have attacked the prosecution’s decision to appeal his prison sentence for murder. They claim Oscar’s case has become “too personal” for prosecutor Gerrie Nel.
A defence source said: “Any decent human being will say the man has suffered enough, let this verdict lie." They also revealed how the 29-year-old Paralympian was “very upset”, languishing in a tiny cell in solitary confinement.
The source said: “Oscar is back in exactly the same cell, we all know he’s suffering enough but tell Nell that, he doesn’t know that, it’s become too personal for him.
“I feel enough is enough. I don’t know what he has against Oscar, I’m very disillusioned about it.
“He’s in (his cell) more or less 24 hours a day, they open the cell for about six hours but just for him to walk up and down the passageway, there’s nothing there.
“He can’t go into a recreational hall or a dining room or an exercise yard or a gym because they are keeping him away from the other prisoners entirely because they are so concerned about his safety.
“They have a tiny room for him with two of three small training things, nothing much, very limited equipment, but he cant go to the big gym.
“There is no TV, no desk, he only has a narrow bed and nothing else. He has no window, no natural light, he doesn’t see any natural light. His cell is three metres by three metres.
“He’s accepted the new sentence but he’s not a happy man. The cell is very lonely.”
A prosecution source said in response: “No comment. We are doing what we are entitled to do under the law.”
