A man was left with serious injuries following a hit-and-run in Brighton.
The 53-year-old pedestrian from Hove was crossing Montague Place in Kemp Town when he was knocked down by a Fiat 500.
The driver failed to stop and police investigating the incident have released graphic CCTV images in a bid to find them.
The Fiat was being driven along Bristol Road before turning left into Montague Place where it collided with the man crossing the road.
It didn't stop at the scene and can be seen to carry on along Montague Place and turning right into College Street.
The car has been traced but police do not know who was behind the wheel at the time of the hit-and-run.
The incident happened at around 3.40pm on Thursday, January 14, and a Secamb spokeswoman confirmed the man was treated by paramedics at the scene for a number of injuries before being taken to Royal Sussex County Hospital.
Despite being flung about a metre above the car by the impact, the 53-year-old was conscious when the ambluance treated him on the street.
Sergeant Dan Pitcher of Sussex Police said: "We are very keen to trace the drivers of the taxi, the silver van, the dark Ford Focus and the black parked car.
"We think you could give us vital information we need to identify the driver.
"Were you the taxi driver and do you have a dash camera which may have captured the Fiat as it drove past?
"Were you in the silver van and did you notice who was driving as the Fiat approached the junction?
"The Ford turned before the Fiat and you may have seen something in your rear view mirror.
"We believe the woman in the parked car was in it during the time of the collision, did you see what happened?
"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."
