The arrest took place on the night of Friday 6 November 2026, at around 10pm, in Comunidade Leonel Brizola in the Vila Luizão area of São Luís.[1] Officers of the 40th Battalion of the Military Police, deployed on Operation Muralha Metropolitana, spotted a man on a motorcycle whose behaviour seemed suspicious.[2] He tried to escape but was overpowered and searched.[2] The suspect entered a house in the community, where officers contained him.[1] Police identified the rider as Émerson Lucas.[1] On him, officers found R$1,000 in cash and small portions of a marijuana-like substance.[1] He was also carrying an iPhone 14.[1] A records check showed the phone was flagged as stolen, prompting an initial arrest for receiving stolen goods.[1] He was taken with all the seized material to the Civil Police central duty station at Cohatrac for the formal record.[1] He remained in custody for drug trafficking.[2]
A search of the house turned up eight pressed bricks of marijuana.[1] Officers also found portions of hashish, skank and cocaine.[1] The seizure further included a packet of hallucinogenic mushrooms, cocaine-like substances and five packets of ecstasy.[2] Police seized a Taurus G2C pistol in 9mm calibre.[1] They also seized two precision scales, rolls of plastic wrap and ziplock bags.[1] The grey Honda CG 160 motorcycle, which had no plates, was seized as well.[1]
The operation was part of Operation Muralha Metropolitana, an effort against drug trafficking and irregular vehicles in the metropolitan region.[1] The 40th Battalion’s command coordinated the action as part of its preventive and repressive work in the capital.[1]
