Gendarmería officers of Escuadrón 12 “Bernardo de Irigoyen” stopped a Toyota Hilux on Ruta Nacional 101 at the Misiones town of San Antonio at 1 a.m. on 15 April 2026.[1] The pickup’s cargo box was covered with a black tarpaulin, and when the occupants lifted it officers found 23 boxes of different sizes that gave off a strong smell of marijuana.[2] The two occupants were an Argentine and a Paraguayan national.[2]

Officers pulled pressed packages, heat-sealed bags and waxed-paper wrappings out of the boxes, holding a vegetable substance and a compact greenish-brown mass.[1] Narcotest field tests were positive for 925 kilos 400 grams of cannabis sativa and 5 kilos 250 grams of hashish.[1] Gendarmería described the hashish as made from the resin stored in the marijuana flowers and later kneaded, with a higher THC level.[1]

The Federal Court and Federal Prosecutor’s Office of Puerto Iguazú took part in the case, and officers detained the two adult occupants, seized the drug and took the vehicle.[1] La Gaceta, reporting the same operation on 16 April, also put the haul at 925 kilos 400 grams of cannabis sativa and 5 kilos 250 grams of hashish.[2] El Liberal published the same agency text the same day and put the combined haul at more than 900 kilos.[3] Two people were detained in the operation, according to Diario Síntesis, which reported the load as more than 930 kilos of drugs.[4]
