Revenue officers have seized almost 140 Kgs of cannabis, with an estimated value of €2.8 million at Rosslare Europort.
The seizure was made yesterday evening by Revenue Department after they stopped and searched a Spanish registered articulated lorry and trailer that had arrived on a ferry from Cherbourg, France.
A man in his 40s was arrested at the scene and taken to Wexford Garda station after the drugs were seized on Wednesday.
In a statement from Revenue, the drugs were discovered concealed within a consignment of vegetables.
Revenue has said that investigations are ongoing.
