South African prison officials say Oscar Pistorius was treated for injuries at a private hospital and has returned to a jail where the Olympian is serving a six-year sentence for killing girlfriend Reeva Steenkamp.
Singabakho Nxumalo, a spokesman for the correctional services department, said Sunday that Pistorius told officials that he suffered injuries after falling out of bed.
Nxumalo did not provide any detail on the injuries, citing medical privacy concerns.
According to reports he had visible injuries to his wrists.
He says the former track star was taken back to his Pretoria prison cell on Saturday, and that an investigation is underway.
Last month, South African prosecutors said they would appeal Pistoriusâ six-year jail sentence, saying it was too lenient.
Pistorius fatally shot Steenkamp in his home on Valentineâs Day 2013.
