Two men have been arrested during an operation in which gardai seized 2.14 million euro worth of cannabis and more than 230,000 euro in cash.
Gardai said the intelligence-led investigation was targeted at transnational drug trafficking networks.
Officers attached to the Garda National Drugs & Organised Crime Bureau (GNDOCB) intercepted a vehicle in the Finglas area of Dublin and conducted a coordinated search of a residence in the Donore area of Co Meath on Wednesday.
The two men aged in their 30s were arrested in connection with the investigation and detained under drug trafficking legislation in Co Louth.
Following the operation, Detective Chief Superintendent Seamus Boland, head of the GNDOCB, said: “This substantial seizure of cannabis and cash once again shows the vast profits being made by transnational organised crime groups, from casual drug use across Ireland.
“There is a direct link between personal use drugs consumption and the violence and drug-related intimidation being experienced in communities. We, in An Garda Siochana, will continue to disrupt the drugs networks bringing drugs into our country and to make Ireland a hostile environment for these criminals to operate. Demand fuels supply.
“Please think before you use this festive period and play your part in making your community safer.”
Investigations are ongoing.
