A MAN was being quizzed today following the discovery of a major oil laundering plant.
Gardai and customs officials carried out a dawn raid at the plant in Co Monaghan – which had the capability to launder 15m litres of fuel a year.
The raid took place at a premises in Drumacon, near Castleblayney, following a long- running surveillance operation.
One man was arrested at the scene and was today being questioned at Castleblayney Garda Station.
According to the Revenue Commissioners, the plant itself was capable of of 'washing' the dye from 15m litres of diesel every year.
The operation had the potential to cause an €8m loss to the exchequer per annum.
A forklift, 6 vehicles and ancillary equipment were seized during the raid.
In a follow up search at a premises in Longfield, a tanker with 20,000 litres of fuel, a trailer with a concealed tank and 68 bags of bleaching earth were discovered.
Investigations into the operations were continuing today.
In a statement, Revenue emphasised the risks posed to vehicles by laundered fuel.
"Revenue would like to take this opportunity to remind motorists and the public that they should be aware of the risks posed to their vehicles by using laundered fuel. It also takes much needed funds from the Exchequer; hurts legitimate trade and of course it is funding criminal activity," a spokeswoman said.
