Derek McGraw Ferguson and William Paterson sought in Spain
Police investigating two unsolved murders - one involving Glasgow gangster Kevin 'Gerbil' Carroll - have made an appeal in Spain.
Officers from the Strathclyde force have held a news conference in Madrid in a bid to trace Glasgow men Derek McGraw Ferguson and William Paterson.
Police want to trace Paterson, 32, over the fatal shooting of Kevin Carroll in Glasgow in January 2010.
Ferguson, 48, is wanted over the fatal shooting of Thomas Cameron in 2007.
The 49-year-old barman was shot in the car park of the Auchinairn Tavern, Bishopbriggs, East Dunbartonshire.
Mr Carroll was repeatedly shot in the car park of Asda supermarket in Glasgow's Robroyston area.
Speaking at news conference in Madrid, Ch Sup John Cuddihy said: "We will do everything possible to trace both fugitives, bring them to justice and remove them from your country.'Extremely violent'
"There is no doubt in my mind that to evade police for this period of time both these men have been receiving assistance from associates.
"Officers are currently and will continue to be on the ground in Southern Spain in areas these two men are known to frequent, to give information to locals and business owners about these men and how they may well be living amongst hard working, honest people in their communities.
Ch Sup Cuddihy said he had no information that either man was a danger to the public.
He added: "However, the crimes they are wanted in connection with are extremely violent and I would urge the public not to approach them at all."
As well as the news conference, officers from Strathclyde Police will also be speaking to locals in Southern Spain and business owners to hand out a Crimestoppers leaflet, printed in Spanish, with pictures of the two men and an appeal for information.
