Between Friday 11 and Saturday 12 September 2026, military units located 23 underground hiding places holding pressed marijuana inside the Paso Bravo natural reserve in the district of San Carlos del Apa, Concepción department.[1][2]

Troops began removing the stock on Sunday 13 September, and by that day the contents of 11 of the 23 deposits had been transferred toward the headquarters of the Comando de Operaciones de Defensa Interna in Arroyito.[2] Rain in the region affected road conditions and slowed transport, so weighing of the pressed-marijuana packages was expected to begin the next day.[1]

Anti-drug prosecutor Pablo René Zárate ordered the whole load moved to the CODI base, where conditions for the work are better.[1] The caches, known as caletas, lay near a former clandestine airstrip reportedly used for cocaine trafficking, and they grew smaller with distance from the main road.[1]
