Gendarmerie officers of Reinforced Section San Jose and Apostoles Group of Squadron 8 Alto Uruguay were deployed on Provincial Route 1 at San Jose.[1] At kilometre 1 they stopped a semi-trailer truck driven by an adult man that had come from Dionisio Cerqueira, Brazil, and was bound for Buenos Aires.[1] The driver presented a remittance for furniture from Brazil, and narcotics dog Leon reacted excitedly at the semi-trailer.[1] A mobile scanner then showed foreign bodies inside the trailer.[1]

Officers searched the load and found large parcels carried on 1,013 wooden boxes.[1] Inside the parcels officers found 2,035 rectangular and shapeless bricks smelling strongly of marijuana.[1] Field Narcotest tests confirmed the bricks as 1,544 kilos 54 grams of cannabis sativa.[1] The truck driver was detained.[1] El Territorio identified the detained driver as an Argentine citizen.[2] In Puerto Piray a motorized patrol of Squadron 10 Eldorado saw a group carrying bundles from the Parana River toward a path into adjoining woods and ordered them to halt.[1] The carriers dropped the load and escaped into the dense vegetation.[1] Officers combed the area and found 11 bundles holding 244 kilos 400 grams of marijuana buds.[1]

The Posadas and Eldorado federal prosecutors ordered seizure of all the drugs, the truck, two cell phones and currency.[1] The Eldorado prosecutor ordered continued inquiries to find those responsible for the Puerto Piray load.[3]
