POLICE in Forth Valley are appealing for a potential witness of a fatal road collision to come forward. 

Menstrie man Ryan Muir sustained serious injuries after a silver MG ZR careered off the A91 at Blairlogie into the wall of a property before striking a tree and coming to a halt. 

The incident happened 50m west of the junction with Manor Loan at around 9.15pm, on Wednesday, November 1.

The 26-year-old was taken to Forth Valley Royal Hospital, where he later passed away. 

Road Policing Officers are now eager to trace the driver of a white car, which they believe was overtaken by the MG ZR and another vehicle moments before the collision.

They say this individual would most likely have seen the MG ZR leave the road and could have information that can assist in the investigation.

Sergeant David Ross from the Road Policing Unit at Stirling said: "I want to stress that the driver we want to trace has done nothing wrong but may have vital information relevant to our ongoing inquiries.

"Unfortunately we do not know the make or model of the car they were driving, other than it being white, so if you were on the A91 at Blairlogie on the evening of Wednesday 1st November while driving a white car and witnessed the MG ZR leaving the road then please contact us immediately."

Those with information can contact the Road Policing Unit at Stirling via 101 and quote incident number 4163 of November 1.
