Paralympic champion Oscar Pistorius is 'unwilling' to contemplate a return to training after he was spotted on a running track in Pretoria.

The 26-year-old, who is on bail ahead of a trial for the murder of his girlfriend Reeva Steenkamp, was photographed at an abandoned track at Pretoria University.

The double amputee's family released a statement saying: "Oscar is not back on any official training programme. This may change in future, but this will be a decision taken by Oscar, and Oscar alone. At this point Oscar is still in an extremely traumatised state and has made it clear to all of us that he is not able or willing to even contemplate this issue at this stage.

"We can confirm that we did have a meeting with Oscar yesterday where various family members and his trainer were present. We all encouraged him to get back onto the track to help stabilise him emotionally.

"Oscar has been out running on a number of isolated occasions in the days following the relaxation of his bail conditions, but each time has been very difficult and he has struggled immensely with the decision to even leave the house."

Pistorius is accused of shooting Steenkamp dead through a bathroom door at his home on Valentine's Day.
