According to DRPS, Vieira has been charged with four counts each of robbery with an offensive weapon, pointing a firearm, use of imitation firearm in the commission of an offence, disguise with intent, possession of property obtained by crime, and possessing a weapon dangerous to public peace. He was also charged with one count of possession of a Schedule III substance for trafficking. Police said Vieira was held for a bail hearing.
