Cigarettes and tobacco have been seized in Revenue operations in Wexford and Tipperary.
On Saturday officers seized over 24,000 cigarettes following a search of a premises in Enniscorthy, with the help of detector dog Gus.
The cigarettes - branded 'Blue River', 'Excellence' and 'Email' - had a retail value of around €16,400, with a potential loss to the Exchequer of more than €12,900.
A man aged in his 50s was questioned in relation to the seizure.
In a separate, intelligence-led operation last week, officers also seized 19.6kg of roll-your-own tobacco following a search of two premises in Nenagh, Co Tipperary.
The seized tobacco, branded 'Amber Leaf', had a retail value of approximately €11,500 and represents a loss to the Exchequer of some €9,600.
A man in his early 20s and a woman in her late 40s have been interviewed.
Investigations are ongoing with a view to prosecutions in both seizures.
