A reward is being offered for the whereabouts of a missing murder suspect who is one of Scotland’s most-wanted fugitives.

Barman Thomas ‘Tam’ Cameron, 49, was shot dead in the car park of the the Auchinairn Tavern in Bishopbriggs where he worked back in 2007.

On the 14th anniversary of the killing, police have released photos of suspect Derek McGraw Ferguson, including a photo of the fugitive from the time and computer-generated images of what he may look like now.

A global manhunt was launched after the dad-of-three’s death, with Mr Ferguson believed to have fled abroad.

Officers suspect the he has travelled between Ireland, Portugal, Holland, Turkey and Spain under an assumed name, and think he may now be based in Spain among criminal associates.

Police have previously said that the 57-year-old from Possil, Glasgow was bald, with green or blue eyes and is 5ft 1in.

He also had tattoos of an arrow and heart design with a dagger, while part of his left ear was missing and he has used an Irish accent in the past.

Crimestoppers are offering rewards of £5,000 to anyone who is able to provide information that leads to his arrest.

Detective Superintendent John Wyllie, who is leading the investigation, said: “I am continuing to appeal for anyone who has any knowledge of Ferguson’s whereabouts to get in touch with any information which could help us trace him.
