Oscar Pistorius treated in hospital for injuries suffered in prison

Convicted murderer Oscar Pistorius was treated in hospital Saturday after suffering injuries to his wrists while in prison, according to South Africa's Correctional Services Department.

Pistorius had sustained minor injuries to his wrists, Manelisi Wolela, a spokesman for South Africa's Department of Correctional Services, told NBC News. Pistorius told prison staff he'd been injured while falling out of bed, according to another spokesman for the corrections department, Singabakho Nxumalo.

Pistorius denied "speculations" of a suicide attempt, Wolela said.

Pistorius' brother Carl tweeted #alliswell on Sunday afternoon, and hit out at media reports suggesting that the double-amputee had tried to self-harm.

"I have just seen Oscar and he is doing well given the circumstances," Carl Pistorius wrote.

"He slipped in his cell and injured himself, nothing serious. Please don't believe the media reports."

The former Paralympic champion was taken to the Kalafong hospital in Pretoria and returned to prison later in the day, Nxumalo said.

Pistorius, a double-amputee, was sentence to six-years' prison in July for the murder of his girlfriend, Reeva Steenkamp, on Valentine's Day 2013. Prosecutors say they plan to appeal that sentence, calling it "shockingly lenient."
