Almost 2 tonnes of cocaine with a market value of more than 400 million euros ($440 million) were found floating at sea off eastern Sicily, in what Italy's tax and customs police on Monday called a record seizure.
The drugs were stored in about 70 waterproof packages, carefully sealed, held together by fishermen's nets and equipped with a luminous signalling device, the Guardia di Finanza said in a statement.
The "peculiar packaging methods and the presence of a luminous device to allow tracking" suggest the haul was dumped at sea by a cargo ship in order for it to be recovered later, the statement added.
