Fife Police are looking for the driver of a silver Vaxhaull Astra five-door hatchback, after they confirmed the death of a cyclist in between St Monans and Elie was the result of a hit-and-run.
Scott Walker (43) was found with serious head injuries on the A917 on Monday July 8.
He died at Ninewells Hospital on the Tuesday.
Following a post-mortem and police inquiries, police confirmed Mr Walker had been involved in a collision with a car which had then left the scene.
Detective chief inspector John Anderson from Fife CID said:
“We are now confident that Mr Walker was involved in a collision with a vehicle as he cycled east from Elie towards St Monans on Monday evening, and that the vehicle was a silver Vauxhall Astra five-door hatchback.
“Through inquiries, we know that the vehicle will have travelled from Elie before the incident and following the collision has continued along the A917 eastbound towards St.Monans.
“We would ask any owners or users of such a car in the East Neuk area of Fife to contact us so that they can be eliminated from our inquiries."
He continued: “I firmly believe that the answers lie in the local community of the East Neuk of Fife.
Does a friend, neighbour, or someone you know drive a silver Vauxhall Astra? Would this have been driving in the area between Elie and St Monan’s last Monday night? It may not appear damaged or indeed you may not have seen it since. Has someone confided in you about what happened?
"If you have any information regarding what happened or a vehicle matching this description, please come forward and contact officers."
Anyone with information can contact Police Scotland 101, quoting incident number 3910 on July 8.
