Jailed South African Paralympian Oscar Pistorius has received treatment in hospital for wrist injuries, prison officials say.

Pistorius told officials that he suffered the injuries after falling out of bed, said Singabakho Nxumalo, a spokesman for South Africa’s correctional services department.

Newspaper City Press said that Pistorius, known as Blade Runner for the carbon-fibre prosthetics he wore when racing, quoted a security guard as saying: “He had bad cuts on his wrists and the doctors kept wrapping bandages around them.”

An inmate situated close to a separate hospital annexe within the prison told the paper Pistorius had injured himself intentionally, and it quoted two warders as saying razor blades were found in his cell.

Pistorius was returned to his cell on Saturday, and an investigation is underway.

“Oscar Pistorius denied speculations of a suicide attempt,” another Department of Correctional Services spokesman said on Sunday, describing the athlete’s injuries as minor.

Asked to comment, Pistorius family spokeswoman Anneliese Burgess said there would be no statement at this stage.

Last month, South African prosecutors said they would appeal Pistorius’ six-year jail sentence, saying it was too lenient.

The double-amputee athlete, who was sentenced on July 6, could be released on parole after three years.

The prescribed minimum sentence for murder in South Africa is 15 years, though a judge can reduce that penalty in some circumstances.

Pistorius also previously served one year in prison for manslaughter for shooting 29-year-old Steenkamp, a model and reality TV star.

That manslaughter conviction was upgraded to the more serious offence of murder after an earlier prosecution appeal, leading to a new sentencing.

Pistorius shot Steenkamp multiple times through a toilet cubicle door in his home in the pre-dawn hours of Valentine’s Day, 2013.

Pistorius testified that he killed Steenkamp by mistake, thinking there was an intruder hiding in the bathroom.

Prosecutors said he shot her intentionally after an argument.

Pistorius and his longtime coach, Ampie Louw, said before Steenkamp’s killing that they wanted to retire together at the Olympics in Rio de Janeiro.
