This shocking video footage shows the sickening moment a pedestrian was mowed down by a hit-and-run driver in Derbyshire.
Police say the collision has left the 19-year-old male victim in a wheelchair with life-changing injuries, following the indicent in Derby.
The man was crossing a road when a dark car, believed to be an Audi A3, approached at speed.
The teenager was sent flying into the air and landed metres away along the pavement in shocking footage which has now been released as part of the police investigation.
The harrowing incident took place at about 7.30pm on November 5, last year, but information has just been released to the media.
Police have never recovered the car and hope by releasing the footage, someone who knows where it is or has information about who was driving will contact the force. The incident happened in Normanton Road, Derby.
Superintendent Adrian Gascoyne said: "The man involved in this collision was just crossing the road when he was struck by a car travelling at considerable speed.
"The footage shows just how shocking the collision was. He is lucky to be alive, and although he survived, he was left with serious injuries and now faces a long spell of rehabilitation.
"It is absolutely essential that we bring the people responsible to justice. I would call on anyone who has information to watch the footage and put yourself in the shoes of the victim, his friends and family.
"If you know who was driving that car, or if you know where the car is now, please get in touch. Even if you just have a suspicion, that piece of the jigsaw could be the one we need."
Police would also like to talk to anybody who has a dark, possibly grey Audi A3, which had a bumper, bonnet and windscreen damage around November 5.
Anybody with any information is asked to call the force collision investigation unit on 101 and quote reference 17000480371.
