Large-scale bank robberies have become more common in Brazil in recent years, with hostages occasionally being used as human shields.

In August, bank robbers armed with explosives and high-powered guns scared a city in the Brazilian state of Sao Paulo, marching hostages down a street and strapping some to their cars as they fled.

In December, large bands of bank robbers stormed cities on both sides of the country, taking hostages and overcoming police garrisons once more.
