Detectives have dealt a serious blow to an eastern European gang suspected of running a lucrative drugs patch in the capital after seizing €300,000 worth of cocaine.
Gardaí also recovered a semi-automatic handgun and ammunition during a series of raids in west Dublin.
A 29-year-old Lithuanian national was arrested during the operation carried out by the Drugs and Organised Crime Bureau (DOCB).
The man was arrested in the Clonee area and is being held at Blanchardstown Garda Station. He can be detained for up to seven days.
Detectives believe he is linked to a major drugs outfit in the capital who control a distribution network in Tyrellstown and the surrounding areas.
The gang is one of a number of eastern European-based groups who have expanded their networks here in recent years.
Assistant Garda Commissioner John O'Driscoll, who oversees operations into organised crime, said the latest seizure shows the force "continues to target those who are suspected to be involved in organised and serious crime and to attempt to locate and seize the drugs they intend to sell within our communities and fire- arms they possess for the purpose of inflicting harm on others".
A series of raids was carried out in west Dublin on Satur- day and Sunday by the DOCB with the assistance of members of the local drugs unit based at Blanchardstown garda station
"During the course of these searches, a quantity of a substance now confirmed to be cocaine with an estimated street sale value of €300,000 was located and seized," a garda spokesperson said.
"A semi-automatic firearm and ammunition was also seized."
The garda's anti-organised crime unit conducted searches last month in Dublin, Cork, Waterford and Kerry as part of a operation targeting a separate Lithuanian gang.
The operation, carried out with Lithuanian authorities and the PSNI, helped dismantle a mob involved in human-trafficking and drug dealing on an international scale.
