Hundreds of kilos of heroin with a street value up to £40 million have been uncovered in one of the UK’s largest drug seizures.
The National Crime Agency (NCA) said an "intelligence-led investigation" allowed British, Belgian and Dutch police to track a container ship suspected of carrying a large drug haul.
When it docked in the Suffolk port of Felixstowe, 389kg of the class A drug were found in one of the containers onboard, hidden under towels and bathrobes. The discovery has led to several arrests.
The vessel is believed to have set off from Oman and had made various stops on its way to the Belgian city of Antwerp.
The day after it arrived in the UK Border Force officers and the NCA removed the heroin from the container and allowed the ship to continue its journey.
Upon the ship's arrival in Antwerp, the now-empty container was transferred by lorry to Rotterdam under police surveillance. Here, Dutch police made two arrests as suspects attempted to unload the contents.
Meanwhile, a man from Worcestershire was also arrested and is still being questioned.
Regional operations manager Colin Williams said: “The seizure of such a large quantity of heroin is the result of a targeted, intelligence-led investigation, carried out by the NCA with international and UK partners.
“It is almost certain that some of these drugs would have been sold in the UK, fuelling violence and exploitation including what we see in county lines offending nationwide.”
