The suspects, who had been under surveillance since December, opened fire as officers arrived, police said. Authorities reported seizing a .50-caliber machine gun, rifles and explosives at the site.
Large-scale bank heists have become common in Brazil in recent years, often involving hostages used as human shields. In October 2021, police killed 25 suspects in a similar operation targeting a gang. Two months earlier, in August 2021, robbers had terrorized another city, marching hostages through the streets and strapping some to their cars during their escape.
