A LARGE scale illegal fuel laundering plant has been uncovered by customs.
The black market operation, which could have processed 15 million litres of fuel a year, was found in Drumacon, Co Monaghan.
Officers from Revenue's Customs Service supported by the Garda Regional Support Unit and local officers raided the plant early this morning.
When running the operation would have cost the state about eight million euro a year, customs said.
A forklift, six vehicles and ancillary equipment used in the laundering process were seized from the site.
Seven tonnes of toxic waste, the by-product of laundering fuel, was also found along with a tanker with 20,000 litres of fuel, a trailer with a concealed tank and 68 bags of bleaching earth in a connected raid at a commercial premises in Longfield.
The raid was carried out following an intelligence-led operation and investigations are ongoing, customs said.
