Officials from Louth County Council have begun a clean-up operation after containers of highly toxic sludge were abandoned in the county.
Up to 15 containers containing 1,000 litres of the sludge, a by-product of diesel laundering, was found just south of the border yesterday evening.
It is a highly dangerous, acidic material left behind after red diesel is 'washed' to remove the coloured dye before it is sold on as ordinary road diesel.
This is the largest discovery of this type of material for many months.
Gardaí have appealed for anyone with information about the discovery or the diesel laundering operation behind it to come forward.
