Gardaí (Irish police) have seized 44kg of cocaine with an estimated value of €3.1m (£2.7m) in County Wicklow.
The drugs were discovered during a search of a vehicle as part of what the force called a “day of action” on Thursday.
Thirty-seven homes, businesses and vehicles were searched throughout locations in counties Dublin and Wicklow.
A total of €353,000 (£301,000) in cash was seized in the operation and more than €280,000 (£240,000) frozen in bank accounts.
Eight vehicles, estimated to be worth more than €200,000 (£171,000) were seized.
Jewellery, designer watches and electronic devices were also seized as evidence of money laundering and proceeds of crime.
Two 30-year-old men were arrested under drugs legislation and remain detained in the Dublin area.
