Spanish police seized 11 tonnes of hashish hidden in truck fuel tanks and arrested 35 people in Madrid and Castilla-La Mancha, the National Police announced on 26 December 2012.[1] Police called the operation Nexi and described it as one of the most important of the last decade.[1]

The gang brought the hashish from Morocco in trucks, which had to refuel constantly because the bundles of hashish left little room in the tanks.[1] The emptied tanks were rewelded in another unit and sent back to Morocco to be loaded with hashish again.[1] The hashish was then hidden in legal merchandise bound for Spain, the Netherlands, France, Belgium and England.[1] A part of the hashish was sent for sale in Madrid and the rest was put into trucks with legal goods, which were driven to Belgium, Britain, France and the Netherlands.[2] Most of the hashish was stored in warehouses in the central Spanish province of Toledo, the BBC reported.[3]

One truck carried about 1,700 kg of hashish and 65 kg of marijuana among tonnes of fresh carrots bound for France and the Netherlands, and a second, driven by the arrested Belgian, hid 8,500 kg of drugs in branded clothing bound for England, the police said.[1]

The 35 arrested included 31 Moroccan nationals, three Spaniards and one Belgian.[1] The investigation by the Madrid anti-drug and organised crime unit began in March 2012 with hashish dealing detected in Leganés, Fuenlabrada and Móstoles.[1] Officers carried out 17 searches and seized 150,000 euros in cash, 14 vehicles and 109 mobile phones, among the vehicles two articulated trucks valued at almost 400,000 euros.[1]

The Vijesti account, quoting the officials’ announcement, says the hashish was smuggled from Morocco in tanker trucks and that those arrested belonged to one of the largest smuggling chains on the European market.[2]
