In São Paulo, there has been a notable rise in robberies conducted by thieves on motorcycles who are now wearing bulletproof vests during their criminal activities. This development is viewed as a significant change in the approach of these criminals, as traditionally, such protective gear was mostly associated with bank robberies or hostage rescues. The use of bulletproof vests by street robbers is a concerning trend for police, highlighting the increasing boldness and preparedness of offenders in the city.

Authorities have recorded multiple incidents where arrested criminals were found wearing bulletproof vests between October 2025 and January 2026, with at least one recent case in February resulting in a murder during a robbery, demonstrating the dangerous escalation of these crimes. Police are particularly concerned that criminals equipped with vests and firearms are more likely to engage in gunfights with law enforcement, increasing the risks involved in apprehending them.

Furthermore, a specialized department within the Civil Police is now investigating the use of bulletproof vests among gangs that target pharmacies specifically to steal high-cost medications. This strategic shift not only endangers the lives of victims and law enforcement personnel but also suggests a broader trend in urban crime strategies where criminals adopt more sophisticated tools and methods to execute their plans.
