SAO PAULO (AP) - Brazilian media are reporting that at least 31 people have been murdered in Sao Paulo in the last three days.
A police spokeswoman says the reported figure is accurate, though she says she has no official statistics.
Early Monday, at least one bus torched was torched in the city.
Police say that a powerful drug gang is behind the wave of violence that's hit South America's biggest city in recent weeks.
They say it's in response to a crackdown on the First Capital Command drug gang, which was allegedly behind a wave of violence that paralyzed the city in 2006.
More than 90 police have been murdered since the start of the year in Sao Paulo. Authorities blame the gang for those deaths.
