Prosecutor questions Pistorius' immobility as re-enactment footage emerges
Defence team says it commissioned footage of athlete, and says TV station obtained it illegally

South African prosecutors yesterday sought to show Oscar Pistorius' sports doctor overstated his immobility without prostheses, as a leaked video shows the star sprinter re-enacting the shooting of his girlfriend.
State prosecutor Gerrie Nel took Wayne Derman to task about his claim the athlete was mentally vulnerable and had limited mobility on his stumps.
Pistorius' defence team says both factors led the Olympian to shoot Reeva Steenkamp in the early morning hours of Valentine's Day 2013 out of fear that she was an intruder.
Nel's tough questioning came as a haunting video of the 27-year-old star sprinter was aired by The Seven Network, an Australian television network.
In the video, Pistorius, wearing a blue tank top and tight black shorts, is walking on his bare stumps with his arm outstretched and hand clenched as if aiming a pistol.
In another clip, Pistorius walks backwards on his stumps, appearing to cast doubt on the defence claim the runner has limited mobility without wearing his prosthesis.
"Can I just ask you then was it ever demonstrated to you that Mr Pistorius was able to walk backwards on his stumps?" said Nel.
