A man has been left in critical condition after being injured in a hit and run near Kilmarnock.
At around 7.05pm on Saturday, he was helping friends move a broken down silver BMW one series onto the back of a trailer on the A77.
The 31-year-old man was then struck by a dark-coloured saloon car which did not stop after the collision.
Police and ambulances attended and he was taken to the Queen Elizabeth University Hospital in Glasgow, where hospital staff have described his condition as critical.
Sergeant Kenny Malaney of the Road Policing Unit based in Govan said: “Our enquiries are ongoing to trace the dark-coloured car involved and its driver.
“At the time of the incident, there was a red Volkswagen Golf parked behind the trailer. The trailer was being towed by a Mercedes GLC.
“If you passed by, please get in touch with officers as you may have information that will assist this investigation.
“I would also appeal to anyone on the road around the time of the crash with dash-cam footage to contact us too.
“Information should be passed to police through 101 with reference number 2803 of February 18.”
