Police have renewed an appeal for witnesses to an accident which led to the death of a 50-year-old Porsche driver.
Strathclyde Police hope to trace the driver of a silver or grey coloured BMW or Audi which was behind the Porsche moments before the fatal crash.
The incident took place on Great Western Road in Clydebank, West Dunbartonshire, on Friday November 2 at around 8.50pm.
The Porsche 911 appears to have lost control on a left hand bend at the West Park Hotel before hitting a barrier, according to Strathclyde Police.
Constable John Hill from the Road Policing Unit, is appealing for people to come forward: "There are a number of people we have spoken to as part of this inquiry. However, I would like to hear from the driver of the silver or grey coloured car, which we believe may have been behind the Porsche before the crash. I would ask that driver to get in touch with us."
Both the driver and his 16-year-old daughter who was his passenger at the time were taken to the Western Infirmary in Glasgow.
The man died shortly afterwards. The teenager has since been released from hospital.
