After a tip to the National Police’s specialised anti-drug department, regional anti-narcotics agents from Concepción ran Operation Aquidabán I on 8 September 2026 at Estancia Sanguina in Yby Yaú, Concepción department.[1][2] Concepción police and the tactical police unit supported the work, directed by prosecutor Pablo René Zárate.[1][2]

Officers cut and burned eight plots: five in harvest stage totalling about 10 hectares and three still growing totalling about five hectares, for roughly 15 hectares in all.[1][2] They also destroyed about 300 kilograms of chopped marijuana spread on a black tarp, seven precarious camps and assorted camp gear.[1][2] Police seized a six-metre aluminium boat without an engine but with homemade oars, which they suspect was used to move drugs and people on the Aquidabán river.[1][2]

ABC Color said police put the economic loss to traffickers at G. 6.795 billion.[1] Concepción al Día said the action was part of the SUMAR anti-drug plan.[2]
