Riot Police Occupy Sao Paulo Favela

230 police officers, dozens of armored cars and two helicopters took over the streets of Paraisopolis, a crowded favela (or slum) in Sao Paulo, Brazil in what BBC News is calling one of the biggest operations in years. Rioting and shooting broke out in the streets after police allegedly murdered a suspect they were attempting to arrest. Protestors set fire to cars, used fireworks as weapons, and looted stores. Three policemen were shot during the uprising and at least two civilians were injured.

All was relatively calm by Tuesday, however police are expected to remain indefinitely. “It is under control in the sense that the most serious and pressing issues have been resolved," said Sao Paulo's public security secretary, Ronaldo Mazargao.
