Four men and one woman were arrested before dawn on Friday 6 November 2026 on the MT-343 between Porto Estrela and Barra do Bugres in Mato Grosso, carrying drugs in two cars.[1] Officers stopped the two cars at around 1am during Operação Faro Protetor das Divisas e Fronteiras, a joint state security-force operation against drug trafficking and other crimes in the border region, and found six sacks of drugs in the boots.[1]

The sacks held 100 kilograms of marijuana, 20 kilograms of skunk, 10 kilograms of hashish, 12 kilograms of coca paste and nine kilograms of cocaine hydrochloride.[1] Police put the damage to organised crime at 979,300 reais, counting both the drugs and the two cars seized.[1] The total seized was described as approximately 150 kilograms of drugs in reports published on 6 November.[2]

The five suspects, the vehicles and the drugs were taken to the Special Border Police Station (Defron) in Cáceres, which handles border crime investigations.[1] The operation brought together Gefron, the border task force, Defron, the 12th Independent Military Police Company of Barra do Bugres, the Porto Estrela military police unit, the BOPE special operations battalion and the Mato Grosso military fire service.[3]

Police had not said where the load came from, where it was going, whether the two cars had travelled together or whether the detainees were linked to a criminal organisation.[1]
