Gerry 'The Monk' Hutch will be extradited to Ireland, after losing an appeal in Spain.
He's wanted here to face charges in relation to the murder of David Byrne in the Regency Hotel in Dublin in February 2016.
The attack saw a group of men, dressed as armed Gardaí, entering the hotel and opening fire at a boxing weigh-in.
David Byrne was shot dead and two other men were injured.
The 59 year-old was arrested in Fuengirola last month, on foot of a European Arrest Warrant.
The gangland criminal appealed his return to Ireland in a Spanish court but lost his appeal.
He's expected to be returned here in the coming weeks.
