15,000 litres of laundered fuel was seized by Revenue officers in Wicklow.

The seizure, which was made today, included 10,000 litres in an oil tanker and 5,000 litres in a tank on a premises in Arklow, Co Wicklow.

The oil tanker transporting the fuel was also seized.

A new fuel marker enables Revenue to test samples of road diesel from distributors, forecourts and transport companies to identify the lower-taxed marked diesel intended for off-road use only, and take appropriate enforcement action where the marker is detected.

Investigations are ongoing in the case, with a view to criminal prosecution.
