A local authority has been forced to spend more than €950,000 cleaning up toxic sludge from fuel smuggling over the past four years.
Louth County Council said it had carried out more than 128 separate clean-up operations since the beginning of 2019 at an average cost of around €6,400 on each occasion.
Figures released by the local authority showed the bill for cleaning up after laundered fuel activity came to almost €300,000 last year alone.
