Four men have been arrested after cannabis with an estimated street value of €8.5m (£7.1m) was seized by gardaí following a search of business premises in Dublin.
Shortly after15:00 local time, gardaí intercepted two vehicles and carried out a planned search in the Ballymount area of Tallaght, where they found 429kg (946lb) of the drug.
Four men, aged 31, 45, 52 and 58, were arrested for facilitating and enhancing a criminal organisation to commit drug trafficking offences.
They are being held at Garda stations in the Dublin area.
Assistant Commissioner Justin Kelly said: “This operation is another example of our commitment to target the enablers and facilitators of global drug trafficking networks and our ongoing efforts to make Ireland a difficult environment for them to operate in.”
The seizure forms part of Operation Tara, an enhanced national anti-drugs strategy.
