The Criminal Assets Bureau has seized motorcycles, cars and cash during a raid on a “heavily fortified compound” in Dublin.
Gardaí said the raid targeted a criminal group aligned to a number of different organised crime gangs around the country.
The search, carried out at the compound in the Crumlin area of the city, involved armed Gardaí, the Air Support Unit and the Customs Dog Unit.
The raid resulted in the seizure of ten motorbikes including a BMW and a Harley Davidson.
A BMW car was also seized alongside a Ford Ranger and a Volkswagen Scirocco.
Some €4,000 in cash was also recovered.
Two men were arrested on suspicion of money laundering offences and taken to Garda stations in Dublin.
Gardaí said the raid marked a “significant development” in an ongoing money laundering and proceeds of crime investigation.
The investigation had already uncovered around €135,000 in different currencies.
