The video shows Oscar Pistorius re-enacting his version of events the night he shot his girlfriend.
“We have no comment … and have nothing to do with the video,” NPA spokesperson Nathi Mncube said on Monday.
The prosecution team for the case, led by Gerrie Nel, had not seen the video which shows the scene of Reeva Steenkamp’s killing, he added.
The documentary, called Running Scared, was broadcast in Australia by Channel 7 on Sunday.
It shows the Paralympian walking and running on his stumps, his sister Aimee lying in the bathroom next to the toilet and Pistorius picking her up and carrying her down the stairs. Pistorius is also seen lying next to the toilet.
Screaming
Beeld newspaper, which watched the video via Skype, said the documentary shows Pistorius screaming “Get out! Get out of my f***ing house!”, and “God, help, please help me!”, and repeatedly “Reeva! Reeva!”
The first scene shows Pistorius in his uncle Arnold’s house, walking on his stumps on two Persian carpets. The second scene shows him walking much faster on the same carpets with his right arm stretched out in front of him as if he was holding a pistol.
It shows a reconstruction of him firing four shots through the toilet door.
Wearing his prosthesis, he is then seen kneeling down and placing Aimee at the bottom of the staircase in his uncle’s house.
‘Breach of trust”
His lawyers issued a statement on Sunday evening describing the broadcast as a “staggering breach of trust” and an invasion of the family’s privacy.
A member of the defence team, lawyer Brian Webber, said Channel 7 had purchased the footage unlawfully. “In addition, during our engagement with Channel 7, we received an undertaking that they would not air any of the material before the end of the trial,” he said.
“While we cannot imagine how any of the footage would not support Oscar’s version, we will only be in a position to comment further once we have had the opportunity to study what has been aired.”
Pistorius has pleaded not guilty to murder.
He said he shot Steenkamp by accident through the locked door of his toilet in his Pretoria home on February 14 2013, thinking she was an intruder.
The State argues he killed her during an argument. – Sapa
