A man has been arrested and 18 searches carried out as part of an investigation into an organised crime gang.
A 152-registration Nissan X-Trail SUV and a 141 Landrover Discovery, seven rolex watches, a GPS tracker and designer clothes were seized during 18 searches in Dublin and Kildare.
Mobile phones, computer equipment and financial documentation were also seized.
A 36-year-old man has been arrested on suspicion of money laundering and is being detained at Irishtown Garda Station.
The target of the operation is a convicted drug dealer and, according to gardaí, one of main figures in the Byrne organised crime gang, which is the Dublin branch of the Kinahan crime gang.
More than 100 gardaí from the Criminal Assets Bureau, the Drugs and Organised Crime Bureau and other specialist and local units raided 18 homes, accountants and solicitors officers, real estate agencies and a motor business.
The raids are part of the investigation into the finances and assets of the drug dealer, his family and associates.
Expensive renovations have been carried out on his home and those of his parents, and associates in Crumlin, Walkinstown, Ballyfermot in Dublin and in Straffan, Co Kildare.
Gardaí say the operation is a significant development in the CAB investigation into the gang's drugs money laundering network.
