The ship - with 23 crew members on board - was stopped off the Canary Islands on May 1. The cargo is estimated to be worth over 800 million euros, equivalent to just over 8.5 billion Swedish kronor.
The seizure beats the previous record from 2024 of 13 tons and Spain's Interior Minister Fernando Grande-Marlaska says the new seizure is "one of the largest, even internationally."
The country's authorities believe that the ship's crew likely intended to repack the cargo onto smaller boats for further smuggling to Europe.
