A pedestrian is in a serious condition in hospital after being struck by a car in a hit-and-run, police said.
The 23-year-old man was crossing a road in Moodiesburn, North Lanarkshire, when he was hit by a silver Ford Fiesta.
The car driver failed to stop following the collision, which happened some time after midnight on Friday.
Emergency services went to the scene, on Stoneyetts Road, near the Gartferry Road junction, and the victim was taken to Glasgow Royal Infirmary.
He remains in hospital in a serious condition.
Police Scotland officers are appealing for information as they work to trace a Ford Fiesta and a grey Vauxhall Corsa.
Both cars were seen driving alongside each other in Central Way, Cumbernauld at 12.08am on Friday.
The cars then travelled along the A8011 and on to the M80, M73, A80 and various other roads in the Moodiesburn and Chryston areas.
The Ford Fiesta headed off towards Gartferry Road after hitting the man in Moodiesburn.
Officers are seeking information about both cars between 12.08am and 12.31am and are asking anyone with dash cam footage from the area at that time to come forward.
The road was closed for several hours to allow police to carry out their inquiries at the scene.
