Former Paralympian Oscar Pistorius taken to medical facility in South Africa

Pistorius was taken to a medical facility for a checkup, officials said.

Logan Maistry, a spokesperson for South Africa's Department of Correctional Services, told ABC News that Pistorius was taken to a medical facility for a checkup but declined to provide further details.

Pistorius is serving a six-year prison sentence for killing his girlfriend, Reeva Steenkamp, on Valentine's Day in 2013.

Pistorius spent a year in prison in Pretoria before he was granted parole and released to house arrest in October 2015.

But South Africa's Supreme Court of Appeals overturned the verdict in December 2015 and convicted Pistorius of murder, ruling that he should have known he might kill someone when firing four shots into the bathroom door. He was sentenced to six years in prison in July 2016 and has been behind bars since.

Pistorius' appeal to overturn the upgraded murder conviction was denied.
