In addition to 39 police officers or prison guards, the dead included 38 suspects and four civilians, authorities said, and inmates were holding more than 120 hostages, including guards and civilians. At one point they held nearly 400.
Since the offensive began Friday, assailants with pistols, automatic rifles, grenades, Molotov cocktails and other weapons had attacked an array of targets, including patrol cars, police and fire stations, banks, a courthouse and bars where off-duty officers gather.
"There's a lot of fear in Sao Paulo -- it's an attack on the police who are supposed to defend the people, who are supposed to provide security in society," De Sa said.
The attacks appeared to migrate from poorer neighborhoods to upscale districts such as Vila Olimpia and Higienopolis, fanning residents' fears amid rumors of more attacks.
Police denied reports that a curfew was planned for sundown Monday, but traffic was jammed earlier than usual as workers left their jobs and headed home.
