A man has been arrested after an estimated £6m worth of cannabis was discovered in a lorry at the port in Belfast.
Border Force officers stopped and searched the vehicle, which contained a consignment of soft drinks, on arrival at the port on Friday.
Three hundred kilos of cannabis were seized and a 45-year-old man from Portadown was detained by National Crime Agency officers.
The NCA believes the "massive" drugs haul could be worth £6m "at Northern Ireland street level".
A spokesperson said losing this amount of drugs will come as a "huge blow to the organised crime group behind this importation".
David Cunningham from the NCA added: "We will continue to work with our partners to stop illegal drugs ending up in our communities.”
