Two 19-year-olds were arrested on the afternoon of Thursday 29 October 2026 during Operação Centro Seguro, a military police operation near the bus terminal in the Junco neighbourhood of Cáceres, Mato Grosso, 220 kilometres from Cuiabá.[1][2] Officers of the 6th Military Police Battalion stopped the two riders of a black Honda XRE 190 after a sudden change of route and behaviour the police called suspicious.[1] CPA Notícias placed the stop on Rua Culturama and said the riders looked back several times as the patrol approached.[3]

A personal search found a black backpack holding two bags with 20 large portions of a substance the occurrence record described as analogous to marijuana.[1][2] The pair told officers they sympathised with a criminal faction and had been instructed to collect the backpack from an isolated plot in a mango grove near a football field behind the Jardim das Oliveiras neighbourhood.[1] Cáceres Notícias, citing that record, said they were then to take the material to the home of one of those involved and wait for further instructions.[1] CPA Notícias reported the destination as the home of a person identified only by the initial W.[3] They also told police they did not know the person who had ordered the drug collected.[1]

They were placed under arrest and taken, handcuffed and without apparent injuries, with the drug and the motorcycle to the Centro Integrado de Segurança e Cidadania (CISC), Cáceres’s integrated public-security centre.[1] The case was registered as suspected illicit drug trafficking and promoting or forming a criminal organisation, for the civil police to investigate.[1] The rider was also issued two traffic notices, one for driving without a licence.[1] CPA Notícias gave those notice numbers as PM00248702 and PM00248703.[3]

When the pair saw the military police patrol approach, the rider of the Honda XRE 190 fled at high speed and officers chased them before the stop.[2]
