(CNN) - Authorities in the UK seized almost 1.3 tons of heroin with a street value of $148 million from a container ship. 

The bust was the UK's biggest involving heroin, according to CNN. 

Officers from the National Crime Agency and the Border Force found the drug hidden in a cargo ship of towels and bathrobes on Aug. 30, according to the NCA.

"This is a record heroin seizure in the UK and one of the largest ever in Europe," said Matt Horne, NCA deputy director of investigations. "It will have denied organized crime tens of millions of pounds in profits."

The ship would have taken the heroin to the Belgian port of Antwerp. 

Removing the drugs took about six hours. Three people were later arrested.
