Jamie Dempsey, 33, changed his looks after his picture appeared on TV, but was caught near Marbella on Tuesday.
The Serious Organised Crime Agency suspect him of being involved with a £12.6million haul of cocaine, seized in 2009.

Dempsey, named as one of Britain’s 10 most wanted men, was traced to a villa complex in a joint operation by Spain’s National Police and the paramilitary Civil Guard.
He is being held at a high-security prison near Madrid, awaiting extradition proceedings at the National Criminal Court.
If he agrees to return to Britain, a Soca escort will take him back within the next two weeks.
But if the Essex man decides to fight, the case could take months.
