Kinahan lieutenant Liam Byrne has been a target for the UK's top crime agency for up to six years.
Senior sources have said that the National Crime Agency's interest in the gangster was sparked by a garda raid which also brought down two other senior members of the mob. Documentation seized by the gardai in a raid of the Greenogue industrial unit in west Dublin in 2017 was the beginning of the end for 42-year-old Byrne.
The Crumlin native is in Spanish custody as he fights his extradition back to England. He was arrested in Mallorca on June 4, on foot of an NCA warrant which claims the thug is believed to be involved in the supply and acquisition of firearms.
