Paul Walker’s Deadly Crash on CCTV

CCTV footage that reveals the exact moment that Paul Walker's Porsche Carrera GT careened into a tree and burst into flames has been released - as one witness claimed that the crash was an accident not a drag race.

Accident investigators 'have received eyewitness statements that the car involved was travelling alone at a high rate of speed' the Los Angeles County Sheriff's Department said in a written statement on Monday. 'No eyewitness has communicated the [department] to say there was a second vehicle.'

The surveillance footage shot from a nearby rooftop camera shows a cloud of black smoke billow into the sky in the seconds after the crash, just moments before what appears to be a large detonation sends a huge fireball skywards. The witness who spoke to the Hollywood reporter said that the fire was already burning when he and the star's friends arrived to try and battle the blaze.

There were pieces of the car that flew into the space lot next to the tree. Also, the front fascia of the building next to the crash was about three stories tall and made of glass,' said the driver to the Hollywood Reporter. 'I looked up and saw the crash broke the window at the top of the building. 'I thought, 'That must have been a sizeable crash.'

Moments before Paul Walker took what turned out to be a fatal ride - he posed proudly next to the exotic car that burst on impact in the deadly accident.

Paul was photographed with the red 2005 Porsche Carrera GT that belonged to his friend Roger Rodas. They were attending a fundraiser in Santa Clarita, CA.

We're told the photos and video were taken about 30 minutes before the accident.
