Police Scotland are making a fresh appeal for information into a fatal road traffic collision in Shetland last month.
The incident involved a silver Mini Cooper and a pedestrian, Martin Gray, 59, who died as a result of the injuries he sustained in the collision.
Officers are trying to trace the driver of a small hatchback car which was seen in the area at the time, although it was not involved in the collision.
The incident happened around 11.25am on January 16 on the A970 close to the junction with Gremista industrial estate.
Road Policing Constable Alasdair Mackay said: “Our thoughts remain very much with the family of Mr Gray while we continue with our investigation.
“We believe that the driver of a small dark coloured hatchback may have witnessed the collision but we have not yet traced this vehicle or the driver.
“We do not know the make, although it is of similar size to a Renault Clio or Volkswagen Polo. The car was heading north out of Lerwick towards Voe at the time.
“I would urge the driver or anybody who have information to come forward to help us establish the full circumstances around this tragic incident.”
Please contact the Road Policing Unit in Dingwall by calling 101 with any information, quoting reference NL178/18.
