The Criminal Assets Bureau has taken possession of a home, nine vehicles and over €130,000 in cash in Killarney.
Possession was also taken of funds totalling over €170,000, which had been frozen in accounts.
The Garda Press Office says the seizures were made as part of Operation Tarmac, which has been ongoing for a number of years, and initiated by local members in the county.
Gardaí and officers from the Criminal Assets Bureau took possession of a significant quantity of cash and number of properties today in Killarney.
This arose from a previous raid, which took place in 2017.
Following a High Court application on Tuesday, CAB and gardaí were granted permission to take possession of the following: a detached property at Upper Ballycasheen, Killarney; nine vehicles, which includes five BMWs, two Volkswagens, one Audi and one Mercedes; twelve high-end watches and a Louis Vuitton bag.
Possession was also taken of over €126,000 and £6,900 in cash, along with four bank and credit union accounts with funds totalling €177,000.
The Garda Press Office says this seizure was initiated and directed by local gardaí in the Killarney Garda Division.
