British authorities seized 2.4 metric tons of cocaine in a ship arriving in England from Panama, authorities said Saturday, calling it one of the U.K.’s biggest drug busts in years.

The drugs, valued at 96 million pounds ($132 million), were found under containers on a vessel at London Gateway port, east of the British capital. The shipment was discovered after what officials said was an intelligence-led operation.

Britain’s interior ministry, the Home Office, said it was the sixth-largest cocaine seizure on record.
