Suspected crime boss Daniel Kinahan has been arrested in the United Arab Emirates in relation to alleged serious organised crime offences.
Kinahan, aged in his 40s, was arrested in Dubai over a warrant issued by the Irish courts, Irish national broadcaster RTÉ has reported.
Dubai police say the arrest was made on Wednesday, 15 April after intensive search and surveillance operations.
An Garda Síochána (Irish police) said they were aware of the arrest of an Irish national.
Dubai police have stated that they have arrested him for his alleged role in an international organised crime network.
The arrest comes as part of efforts to combat cross-border crime.
The arrest followed the receipt of a judicial file from Irish authorities detailing Kinahan's alleged crimes and his involvement in an international criminal organisation.
Based on this file, Dubai Public Prosecution issued an arrest warrant to initiate legal procedures ahead of his extradition.
Kinahan was captured within 48 hours of the warrant being issued.
Gardaí say the arrest is in accordance with the bi-lateral agreement on extradition between Ireland and the United Arab Emirates.
They confirmed that the arrest remains a matter for the authorities in the UAE at this time.
In a statement, An Garda Síochána stated: Today's arrest is another extremely important demonstration of the need for international law enforcement cooperation in tackling transnational organised crime.
