MPs have been told that HM Revenue & Customs Officials in Northern Ireland have recouped more than £7m as they attempt to tackle cross-border fuel smuggling.
Barra McGrory QC, Northern Ireland's Director of Public Prosecutions, gave evidence to the Northern Ireland Affairs Committee on 11 January 2012, as part of an inquiry into so-called fuel laundering.
He said that although the principle priority of his office was to punish convicted smugglers and launderers, a key priority was recuperating lost revenue, through confiscating the assets of offenders.
Fuel is smuggled across the border to exploit the differential in duty rates, as petrol duty is lower in the Republic of Ireland than in Northern Ireland.
Smuggled fuel also often has other low duty fuels such as kerosene added to it, which can cause damage to cars.
