Police are appealing for information after a motorist reported that he may have struck a pedestrian on the A92 early on Friday morning.
An investigation has been launched following a collision northbound on the trunk road between Redhouse and Bankhead roundabouts.
A motorist travelling on the Kirkcaldy to Glenrothes road reported that he may have struck a pedestrian walking on the road at about 3.00 a.m.
Officers are appealing for anyone with information that can help identify the pedestrian to contact police, as this person may be in need of medical attention.
Despite extensive searches, police have been unable to locate them.
Inspector Derek Paxton said: “Thanks to an excellent public response to media coverage of this matter earlier today, we are now satisfied that a pedestrian was walking on the A92 northbound between Kirkcaldy and Glenrothes which is known locally as the Thornton Bypass, at about 3.00 a.m. this morning (Friday).
“We believe the pedestrian was struck by the wing mirror of the vehicle involved and it is likely they will have sustained some form of injury.
“The road was closed for several hours to allow a thorough search of the immediate area, but nothing to assist in identifying the pedestrian has so far been found.
“Police Scotland is keen to identify the pedestrian to establish if they need medical attention.
“Our search has been expanded to take in fields and open country near the A92 with police dogs and the police helicopter also having been involved.”
Anyone with information is urged to contact police by calling 101.
