Officers of Bolivia’s Unidad Movil Policial para Areas Rurais (UMOPAR) manning a checkpoint on the Bioceanic highway stopped a truck occupied by two men on Friday 13 November 2026, on the Bolivian stretch between Puerto Suarez and the Brazilian border.[1] The two occupants were arrested for drug trafficking and referred to the procedures of the Bolivian authorities.[1]

A search of the truck found 305 tablets of a substance that tested positive for marijuana in a preliminary test.[1] A second account describes the find as 305 packages of a greenish substance giving a positive field result for marijuana during the search of the tractor-trailer.[2] Officers seized the truck, a second vehicle and three mobile phones, while the total weight of the drug was not disclosed.[1]

Authorities suspect the load was bound for Brazilian territory, possibly the Corumba region, the town across from Puerto Quijarro with a road link to Puerto Suarez.[1] The stop was a UMOPAR drug-trafficking interdiction operation on the Bioceanic highway in the municipality of Puerto Suarez, Santa Cruz, under the Frontera Segura 2.0 - Vias Seguras operations plan.[2]
