Police in Spain have seized seven-and-a-half tonnes of cocaine hidden inside frozen tuna fish. Officers made the discovery in the northwestern port of Vigo on Tuesday (12 December). A police spokesman said the cocaine was from South America and was due to be distributed across Europe. In a second operation, police also found three-and-a-half tonnes of cocaine hidden in shipping containers in the Eastern port of Valencia. A total of 20 people belonging to two organisations of Balkan origin have been arrested, police said, in what they described as a "major blow" to one Europe's most powerful distribution networks.
