A cyclist has been left fighting for his life after being found lying on a road with a head injury in Fife.
The incident is believed to have taken place between 7.30pm and 7.45pm on Monday on the A917 between Elie and St Monans.
Members of the public contacted police after finding the 43-year-old man lying on the road with serious injuries.
He was taken to Ninewells Hospital where he remains in a critical condition.
Detective Chief Inspector John Anderson said: "The male cyclist has sustained serious head injuries and we are actively working to establish if a motorist was involved and did not stop after the incident took place.
"Given the time of day this occurred, it is unlikely any individual would be unaware if they had struck someone, as there would still have been plenty of light.
"I would ask any motorist involved to search their conscience and come forward as a matter of urgency to speak with us and explain the full circumstances of what happened.
"It is likely that any vehicle involved sustained damage as a result of this collision, therefore I would appeal for any information surrounding a vehicle which has been seen with new damage.
"Specifically, I am also looking to speak with the driver of a silver Vauxhall motor vehicle that we know sustained damage on the Elie to St Monans road near to Ardross Cottages.
"Likewise, any other motorists or members of the public who have any relevant information, including anyone with dash-cam footage who may have been travelling in this area of Fife yesterday evening, should also contact police immediately."
