Pistorius and ex-mafia boss Krejcir are football mates in prison

Convicted Paralympics runner Oscar Pistorius has reportedly been videotaped playing football with a former mafia boss in a Pretoria-based prison.

According to reports, the video showcases Pistorius and Radovan Krejcir taking turns in a penalty shoot-out session in an exercise yard at Kgosi Mampuru prison.

Currently, the double amputee athlete is serving a five-year jail sentence for killing his girlfriend Reeva Steenkamp in February 2013.

In light of the concerns that Pistorius and Krejcir were not wearing prison clothing in the video, the department of correctional services stated that offenders were allowed to wear sporting gear while they exercise, the Independent reported.

The six-time Paralympic champion was acquitted of murder charges and was found guilty of culpable homicide, and is expected to be released in August to spend the remainder of his sentence under house arrest.
