A number of car dealers and a Revenue Commissioners official have been arrested as part of a Garda investigation into alleged tax fraud.
The four men aged between their mid 30s and mid 50s were arrested as part of a joint Garda/Revenue Operation, Operation Tie. They are due before a sitting of Tallaght District Court this morning.
It is understood the investigation centres on an alleged fraud involving vehicle registration tax (VRT) on cars.
Operation Tie was co-ordinated by the Criminal Assets Bureau (CAB), National Support Services and the Dublin Metropolitan Regional Traffic Department.
The investigation started in 2007 and involves investigations into “criminal activity, primarily revenue irregularities and profits from criminal activity”, a Garda spokesman said.
A Revenue spokesman said: "We can confirm that an officer has been suspended".
In December 2007, CAB officers seized cars, documentation and a gun in a series of raids on businesses and homes in Dublin. While searches took place throughout the city, the bulk were concentrated on locations in the Dublin 12 / Naas Road area.
Solicitors' and accountants' offices were among those searched in the 2007 raids. A 9mm handgun was discovered in a warehouse close to one of the raided garages. Some 40 cars were taken control of, including Mercedes, Bentley, BMW and Range Rover models.
