Gendarmes from the Orléans research section, the local gendarmerie group and GIGN reinforcements found 3.2 tonnes of cannabis resin at a farm in Sorel-Moussel, a small commune in Eure-et-Loir about 15 km from Dreux.[1]

Ten people were arrested: eight in Dreux and its suburbs, and two at Roissy airport who were about to take a flight to Thailand.[2] Seven of the ten were placed under formal investigation in Paris, including the head of the network.[2]

Investigators also seized 27 weapons, including automatic pistols, rifles, submachine guns and rocket launchers, 320,000 euros in cash and eight vehicles.[2] Police said the network brought the resin from Morocco by boat to Spain and moved it north in convoys of powerful cars registered in Germany or Belgium, hiding it at the Sorel-Moussel farm.[1]

An investigator said the network moved up to a tonne per trip, and a ledger found in the searches suggested it had convoyed 48 tonnes of resin since September 2008, worth 250 million euros.[1] The operation was carried out by about 100 gendarmes from the Orléans research section, the Eure-et-Loir departmental gendarmerie and the GIGN, at the arrival of a go-fast convoy, a French term for a convoy of several powerful cars carrying drugs at speed.[2]
