The two shipments together represented a street value of roughly 600 million euros ($730 million), the prosecutors said, making it the biggest seizure of cocaine headed for the Netherlands. Prosecutors said a 28-year-old Dutchman had been arrested on Wednesday who was registered as the recipient of the containers in which the drugs were found. In Hamburg, Germany, 16.17 tonnes of cocaine were found in over 1,700 tins of wall filler which had arrived on a container ship from Paraguay. In the Belgian port of Antwerp around 7.2 tonnes of the drugs was found hidden in a container filled with wood blocks which had been shipped from Panama.
