Officers of DENARC, the Department of Narcotics, arrested 21-year-old David Silva de Oliveira Filho in Porto Velho’s south zone on suspicion of drug trafficking.[1] The case was recorded under operations Narke and Protetor das Fronteiras.[1] An anonymous tip said the suspect was selling drugs and supplying different sale points across the region.[1] DENARC teams investigated and monitored the suspect, stopping him as he left his apartment to make a delivery and finding three portions of powdered cocaine in his clothing.[2]

Officers then searched the apartment on Rua Baobá in the Cohab neighbourhood and found the remaining drugs hidden inside a refrigerator.[1] In total officers seized 102 portions of skunk amounting to about half a kilogram of that drug.[1] The same seizure included 23 portions of cocaine and four larger portions of that drug weighing about 300 grams, which are not counted in the cannabis total.[2] Officers also collected about R$500 in cash and a motorcycle investigators said was used in trafficking.[1]

The detainee was arrested and taken to DENARC headquarters, where legal procedures were carried out.[1] Both reports were published on 3 November 2026.[1]
