The ministry said in a statement that the drugs came on board of a ship from Brazil to the port in Lisbon and were hidden in containers with decorative stones intended for a Portuguese company.

"This is the largest volume of drugs ever seized in the port of Lisbon," the statement said.

A 43-year-old Portuguese citizen has been detained in connection with the confiscated drugs. He is suspected of involvement in an international criminal organization, which used Portugal as a gateway for smuggling drugs to Europe.
