Jailed South African Olympic athlete Oscar Pistorius was taken to the hospital for wrist injuries.

A prison service spokesperson said the injuries were "minor" and returned to his prison cell in Pretoria on Saturday.

A report by City Press said Pistorius had been taken to hospital on Saturday.

It said blades had been found in a subsequent search of Pistorius's cell. Pistorius denied speculation of a suicide attempt, the spokesman said.

Pistorius has sentanced six-year jail for murdering his girlfriend Reeva Steenkamp in 2013. The 29-year-old athlete was initially given a five-year term for manslaughter, but was found guilty of murder on appeal last December.

Pistorius has maintained the killing was an accident after he mistook her for an intruder, while the prosecution said he killed her deliberately after the two had an argument.

Pistorius was once one of the world's most admired sportsmen, inspiring millions with the way he overcame his disability to achieve athletic success.

He won six Paralympic gold medals and at London 2012 became the first athlete to compete in both the Paralympic and Olympic Games.
