Oscar Pistorius' parole already has been delayed once. Now his previously reported affiliation with a Czech mob boss may result in further delays.

Officials at the Kgosi Mampuru II prison in Pretoria, South Africa, have confiscated a computer hard drive from the double-amputee Olympic sprinter as part of an investigation into Richard Krejcir, The Telegraph reported.

Oscar Pistorius' Family Afraid "Blade Runner" Still Could Get Murder Conviction At Appeal

The high court of Johannesburg found Krejcir guilty of kidnapping, attempted murder and attempted drug-dealing last week.

Reports surfaced that the two had become friends when they were sharing fitness equipment in the spring, and a video of Krejcir and Pistorius playing soccer in the prison court yard went viral a short time later.

Expert Says Oscar Pistorius Prosecutors Wasting Their Time On Appeal

The raid on Pistorius' computer hard drive took place on May 15, according to The Telegraph.

"We know Oscar and Krejcir were spending a lot of time together in prison, so we wanted to get to all of those who seemed closed to Krejcir," a senior police official told the Sunday Times of South Africa.

Pistorius, currently serving a five-year culpable homicide sentence for the shooting death of girlfriend Reeva Steenkamp on Valentine's Day, 2013, was to have been granted house arrest on Aug. 21 until a justice minister blocked his parole.

A review board will meet on Sept. 18 to consider whether Pistorius should be granted parole. He is also scheduled to go back to court in November on an appeal of his culpable homicide conviction. Prosecutors are hoping to get a murder conviction that carries a minimum 15-year sentence.

Brian Webber told The Telegraph he did not know about the raid but refused to speculate whether it would affect Pistorius' parole review.

Solomon Makgale, a prison spokesman, confirmed the raid on Pistorius' cell but said no evidence of wrongdoing on Pistorius' part has yet been found.

"There is no evidence at this stage to link Pistorius to any criminality, but we are still awaiting analysts reports about the contents of the items confiscated," he said.
