Customs officers have seized more than four million cigarettes at Dublin Port.
The "Sovereign" brand cigarettes arrived in a container of wood burning stoves and would have represented a loss to Revenue of more than €900,000 if sold on the black market. An articulated lorry which arrived to pick up the container was also siezed.
The container had been loaded in the Port of Gdynia, Poland and arrived in Dublin via Antwerp.
The contents were declared to Customs as 216 wood burning stoves, but officers found more than 19,000 cigarettes hidden in each stove. The goods were consigned to a bogus address in the border area.
Today's haul is the eighth commercial seizure of cigarettes or tobacco in freight this year and the first originating in Poland. Previous seizures originated in The Gambia, Greece, Malaysia, Belgium and Spain.
The brand of cigarettes involved and the circumstances in which they were seized would suggest that the consignment was ultimately destined for Northern Ireland, Revenue said in a statement.
