A Scot wanted for murder is to have his face beamed on a giant screen across Spain's "Costa del Crime".

Police have been hunting Derek McGraw Ferguson for seven years for the 2007 killing of Thomas Cameron just outside Glasgow.

They believe the now 51-year-old has fled to Spain and want the help of expats in finding him.

Charity Crimestoppers and the UK's National Crime Agency (NCA) are using a 13ft-high mobile screen to highlight Ferguson and 17 other British fugitives. the tactic for the first time in an attempt to flush

They will take the screen around expat hotspots such oBenidorm, Malaga and Puerto Banus.

It is touring areas with large British contingents and parking outside nightclubs, bars, supermarkets and restaurants.

The campaign is part of Operation Captura, which targets British fugitives believed to be hiding among expat communities in the Spanish Costas.

Scottish and Spanish police had a joint press conference looking for Ferguson in 2012 and he was recently put on the NCA's most-wanted list for Spain.

Ferguson is alleged to have shot dead barman Thomas Cameron, 49, as he left work just before 7pm at the Auchinairn Tavern in Bishopbriggs, East Dunbartonshire, on June 28, 2007.

No-one has been arrested in relation to the shooting but police believe Mr Cameron knew his killers, and that he had arranged to meet two men in the car park outside the pub.

Mr Cameron's 20-year-old son Ross died following an incident at a Hogmanay party in Bishopbriggs 18 months before his father's killing and a man was subsequently convicted of culpable homicide, although police have said previously they do not believe the two crimes are connected.

Asked about the giant screen, Roger Critchell, director of operations for Crimestoppers, added: "This is something that we have never done before but we believe that broadcasting these fugitives' faces right in their back yards will not only encourage the public to speak up but show these individuals that there really is nowhere to hide.

"There will be no avoiding the faces on this screen - they'll be broadcast in all the popular expat areas.

"I would urge anyone who recognises any of those faces to contact Crimestoppers anonymously.

"We don't take personal details and you won't have to give a statement or go to court.

"Many of these fugitives are currently living a life of leisure funded by serious crime. They cannot be allowed to hide forever, they must be brought to justice. Do the right thing and help us find them."

Captura, an initiative between Crimestoppers, the NCA and Spanish authorities, is in its ninth year.

NCA Deputy Director Steve Reynolds said: "We've caught 68 out of 86 fugitives on the Captura list and the rest know we won't stop until we catch them too.

"By taking our campaign directly into Spanish communities where we believe they are living and socialising, their lives will become even more uncomfortable.

"We want British expats and locals to help us by being extra eyes and ears and telling us what they know.

"These fugitives are wanted for serious crimes."

Wanted men include convicted rapist Mohammed Jahangir Alam, 32, from Cheltenham, convicted drug dealer John Barton, 59, from Bradford and Allan James Foster, 43, who is wanted by Northumbria Police in connection with the murder of David 'Noddy' Rice in a car park in May 2006, as well as for drugs and diamond theft offences.
