Gardaí and Revenue officers have seized €740,000 worth of cannabis in a truck arriving from mainland Europe.
The investigation related to “serious organised criminal activity”, the Garda said in a statement on Friday night.
The seizure was the result of a joint operation in Wexford carried out by the Garda National Drugs and Organised Crime Bureau (GNDOCB) and the Revenue Customs Service.
