A father-of-three has been charged with attempted murder after he ran over a gun-wielding teenager who stole a pair of sneakers from him, ripping the younger's arm off.

Phillip Pierre, 39, had arranged to meet Zachary Sam, 17, in Brooklyn, New York, at around 12.30pm on Friday in order to buy a $190 pair of Air Jordan 8 sneakers he advertised on Craigslist.

But when he arrived police say Sam climbed into Pierre's Honda Pilot, pulled out a revolver and took the sneakers before attempting to walk away.

CCTV of the incident, obtained by the New York Daily News, shows Pierre made a U-turn and driving headlong at Sam as he was on the sidewalk, pulling him under the wheels and slamming him into a metal fence, tearing part of his right arm off.

Despite his severe injuries, Sam can be seen squirming out from under the car and struggling with Pierre and several bystanders before fleeing up the street.

According to ABC Sam left his hand behind at the scene, along with the gun, and footage shows his sleeve flapping loosely in the wind as he runs.

According to earlier reports, the boy managed to climb on to a bus further down the street, stunning passengers with his heavily bleeding arm.

The driver is reported to have stopped the bus, allowing Pierre to catch up who then held Sam until the police and ambulance arrived.

Alex Saint Fleur, who lives nearby, said: 'The guy ran him over. He got out, the driver said, "He’s trying to rob me. He’s trying to rob me."

'I saw the gun on the floor. The arm was in the floor near the gun.

'Everyone is screaming, "Come back, come back, your arm. You’re bleeding too much."'

Sam was taken to hospital in critical condition and is now reported to be serious but stable. Doctors had attempted to reattach his hand, but it is unclear if they were successful.

Police say that when he is well enough he will be taken to jail and charged over the armed theft.

Meanwhile Pierre has also been taken to jail and charged with attempted murder.

ABC News spoke to a man called 'Michael', who purported to be Pierre's cousin, who said: 'Two families are destroyed tonight - my cousin, and this kid's family.

'I know what the video's showing - if somebody pulls a gun in your head, and you're trying to get the cops to catch him, what would you do? You're telling me just let him go?'

Meanwhile Raymonde Jason, Sam's upstairs neighbor, added: 'Should we call that instant karma? I don't know what to say. He should not have been putting himself in a situation to rob.'

Pierre, a father-of-three, has now been charged with attempted murder which Sam is expected to be charged with armed robbery once he recovers
