A Scots police officer has been killed while trying to arrest a gunman in Canada.

Constable John Davidson, who is originally from Hawick in the Borders, was shot in Abbotsford, British Columbia, on Monday.

The 53-year-old served with Northumbria Police between 1993 to 2005 before moving to British Columbia.

He leaves behind a wife and three children.

Acting chief constable Winton Keenen, of Northumbria Police, said: "We were very saddened to learn of the death of our former colleague who died bravely in the line of duty while serving as an officer in Abbotsford, Canada.

"Our thoughts are very much with his family, friends and former colleagues at this difficult time.

"Today many of our officers who knew John well during his career with us and kept in touch with him over the ensuing years are shocked by the events in Canada.

"We all want to express our sincere condolences to his family at this tragic news."

Mr Davidson was responding to reports of a stolen car.

A 65-year-old homeless man has been charged with murder.
