A cyclist is fighting for his life in hospital following what may have been a hit and run incident in north east Fife.
Emergency services were called to treat the 43-year-old man after he was found with serious injuries on the A917 between St Monans and Elie at around 7.45pm.
The cyclist was treated briefly at the scene before being rushed to Dundee’s Ninewells Hospital with significant head trauma.
Doctors there have said the man is in a “critical” condition.
Officers are currently investigating the circumstances behind the crash and, while they are keeping an open mind, the probe is focusing on whether the man may have been struck by a vehicle which then failed to stop.
Detective Chief Inspector John Anderson, from Fife CID, 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 of 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.
“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.”
The road was immediately closed at the junction for Elie and was shut for several hours as investigation work started, before it finally reopened at 4am on Tuesday morning.
Anyone who may have witnessed what happened, or the cyclist in the area around the time of the accident, should contact 101.
