Convicted murderer Oscar Pistorius has returned to his prison cell in South Africa's capital after being treated in hospital for injuries sustained in a fall, prison officials said.
"He had to be detained Saturday afternoon at the hospital after falling off his bed," prison services spokesman Singabakho Nxumalo said.
"He's back in our care now," Mr Nxumalo added.
He said the double-amputee Paralympian was again in the medical wing of the Kgosi Mampuru II prison in Pretoria where he has been serving his six-year sentence due to his disability.
According to the South African weekly City Press, citing another inmate at the prison, Pistorius had to go to hospital after intentionally harming himself.
When asked about the report, Mr Nxumalo said: "We can't confirm that, it's only speculation."
A spokesperson for the Department of Correctional Facilities said: "Oscar Pistorius denied speculations of a suicide attempt.
"As a policy principle we cannot further discuss a particular offender's personal condition in the public domain," Manelisi Wolela said.
Pistorius was convicted of killing his girlfriend Reeva Steenkamp, a model and law graduate, in the early hours of Valentine's Day in 2013, saying he mistook her for a burglar when he fired four times through the door of his bedroom toilet.
Pistorius, who pleaded not guilty at his trial in 2014, has always denied killing Ms Steenkamp in a rage, saying he was trying to protect her.
After first being found guilty of culpable homicide, an appeals court upgraded his conviction to murder in December last year.
The 29-year-old is eligible for conditional release in 2019 after serving half his prison term.
