Millions of euros worth of cocaine has been seized and two people have been arrested by gardaí.
It comes after an operation involving personnel from the National Drugs and Organised Crime Bureau on Wednesday.
Gardaí stopped two vehicles in the Swords area of north Co Dublin and also carried out a search of a house in Shankill.
Thirty-eight kilos of cocaine with an estimated street sale value of €2.6 million, €66,000 in cash, a cocaine press, money counters and other drug distribution paraphernalia were recovered.
A 28-year-old man and a 22-year-old woman were arrested on suspicion of facilitating and enhancing drug distribution activities for an organised crime group.
They are currently detained under Section 50 of the Criminal Justice Act 2007, at a garda station in the Dublin region and can be held for up to seven days.
Commenting on the operation, Assistant Commissioner Angela Willis of Organised and Serious Crime said: “This is another significant seizure of cocaine which we believe was destined for the Christmas social scene in particular.
“An Garda Siochana and our law enforcement partners are continuing to play our part in tackling drug-related organised crime and intimidation.
“Think before you use this coming holiday season, as consumption fuels supply and demand in this harmful illicit industry. We all have a part to play.”
Investigations are ongoing.
