Rio de Janeiro: The headquarters of the Sao Paulo state police`s special operations unit was attacked, while at least 10 vehicles were torched in Sao Paulo, Brazil`s largest city, officials said.
Two gunmen opened fire from an automobile on the police special operations facility early Sunday, just hours after someone fired shots at the unit commander`s house.
Officers on duty at the station returned fire, killing one of the assailants when he got out of the vehicle to throw a fire bomb.
The other assailant managed to get away after attacking the police unit`s station in downtown Sao Paulo.
The police station was attacked less than 24 hours after gunmen opened fire on special operations unit commander Lt Col Paulo Telhada as he was getting out of his car in front of his house in the northern section of the city.
The two gunmen fired at least 10 shots at Telhada, who was not hurt in the attack.
"The investigations into the crimes that occurred this weekend are underway and all efforts are being made to find and punish those responsible to the full extent of the law," the state police said.
The attacks are not part of a new offensive by organised crime groups against the police, Sao Paulo Governor Alberto Goldman said.
"I don`t believe that`s the case, but regardless of what I think, we are prepared to deal with any attempt to mount organised attacks," Goldman said.
At least 10 vehicles, meanwhile, were set on fire in six different neighbourhoods in Sao Paulo early Sunday, the fire department said.
The torching of the vehicles was in retaliation for the recent arrests of members of a criminal organisation, police said.
The First Capital Command or PCC, which controls drug and weapons trafficking in the slums of Sao Paulo and other cities, carried out a series of attacks in Brazil`s largest city in 2006.
PCC leaders reportedly run the criminal organization from the prisons of Sao Paulo state, and the gang has become one of Brazil`s largest crime groups.
