A number of official law enforcement agencies were part of a joint task-force that performed 10 searches in locations in Meath, Cavan, and Monaghan.
On the morning of Thursday 5 September, the Criminal Assets Bureau (CAB) targeted the assets and activities of an Organised Crime Gang (OCG) involved in the recent spate of ATM thefts.
During the searches, a working fuel laundering plant was discovered, as well as evidence of offences relating to waste management.
The four professional premises, four residential premises, and two yards were searched by CAB, with the assistance of the Garda Emergency Response Unit (ERU), the Garda Stolen Motor Vehicle Investigation Unit (SMVIU), the Revenue Customs Dog Unit and Revenue Customs (Marked Mineral Oil Unit) and Environmental Engineers.
The CAB seized one vehicle, a quantity of illicit cigarettes, financial documents, documentation in relation to the ownership of assets and a laptop computer.
"This morning’s operation marks a significant development in the CAB operation which has been shadowing the criminal investigation being conducted by local Gardaí supported by national units and follows on from a number of significant seizures of cash and other property by the Gardaí over the past number of weeks." a Garda statement read.
"The CAB investigation relates to cash, vehicles, other assets and real estate property that may represent the proceeds of crime."
