Gendarmeria Nacional Argentina seized 649 kilos 800 grams of marijuana in two operations in northern Misiones, at Caraguatay and Colonia Mado.[1] A motorised patrol of Squadron 10 Eldorado turned off National Route 12 onto a dirt road known as Cementerio in Caraguatay after seeing recent vehicle tracks.[2]

With support from the Eldorado complex-crimes investigations unit and the Montecarlo section, officers combed the wooded area and found four abandoned bundles holding 216 rectangular packages.[2] Narcotest field tests confirmed the Caraguatay bundles held 154 kilos 400 grams of cannabis sativa.[2]

Two hours later, officers of the Nucleo section of the same unit saw people in a canoe trying to cross the Parana River at a spot called El Frances, in Colonia Mado.[2] Seeing the gendarmes, the canoe occupants threw bundles onto the Argentine bank and fled towards Paraguay, and no arrests were reported.[2] A search of the riverbank found 22 bundles of different sizes and colours.[2] Taken to the squadron base with a magistrates authorisation and weighed, 10 of the Colonia Mado bundles held buds and the rest pressed marijuana, 495 kilos 400 grams in total.[2] Noticias de la Calle likewise reports that those on board threw bundles onto the Argentine coast and escaped quickly towards the Paraguayan side.[1]

The Federal Court and the Federal Prosecutors Office of Eldorado authorised the seizure of the drug and opened proceedings under drug law 23.737.[2]
