Graphic footage of a pedestrian being left for dead after he was struck in a high-speed hit-and-run crash has been released by police.
The 53-year-old victim is seen being flung violently into the air after being hit by a Fiat 500 as he crossed Montague Place in the Kemptown area of Brighton.
A witness could be seen holding their hand to their mouth in apparent shock at the point of impact at 3.40pm on Thursday January 14.
As the victim lies sprawled motionless in the middle of the road, passers-by are seen standing around in disbelief.
The victim, who has not been named, suffered serious injuries but is recovering, said Sussex Police, who want to trace the drivers of a taxi, a silver van, a Ford Focus and a black parked car for clues.
Sergeant Dan Pitcher said: "We are keen to speak to anyone who saw what happened or can give us information which will help with our investigation.
"The Fiat drove off, leaving the victim for dead, and clearly they would have known they had hit someone.
"The pedestrian, a man from Hove, suffered serious head injuries and is thankfully making a recovery."
Anyone with information is asked to call Sussex Police on 101, quoting Operation Northdown.
