A police sergeant who pinned a pedestrian to a wall with his vehicle after losing control on an icy country road has been found guilty of careless driving.

Allan Masson was on his way to a court trial when his police car struck 69-year-old Joseph Leghorn on an unclassified road in Aberdeenshire.

Mr Leghorn was thrown on to the bonnet of the car and his legs ended up pinned between the vehicle and a stone wall on March 21, 2013.

He suffered broken bones in his leg and foot and fractured ribs in the accident.

He spent a week in hospital where he had a titanium rod fitted in his leg and lost one of his toes.

Masson, 43, was on trial at Aberdeen Sheriff Court last month accused of seriously injuring Mr Leghorn, of Dunfermline.

He was charged with dangerous driving by going at excessive speeds for the road conditions.

But yesterday Sheriff William Taylor found him guilty of the lesser charge of careless driving.

Masson, who has nearly a decade of service with the force, was fined £500 and had three penalty points put on his driving licence.

Masson, who is also a volunteer with the Braemar Mountain Rescue Team, had said he was going down a hill at 15 to 20 mph when he lost control while braking in the light wintry conditions.

But other witnesses told the trial that the police car was going "quite quick" compared to other vehicles navigating the same stretch of road.

The court was told that Masson may still face disciplinary action from Police Scotland.

He declined to comment when leaving court.
