More than 11,000 litres of alcohol, with a retail value of €403,000 has been seized by Revenue officers at Dublin Port.
The alcohol was discovered by officers during routine operations last Wednesday.
The smuggled alcohol, which included over 10,200 litres of blended scotch whiskey and 800 litres of alcopops, represents a potential loss to the exchequer of over €255,300.
Officers discovered the smuggled alcohol when they searched a trailer which had originated from Poland.
Investigations are ongoing.
