Dynamite was used to blow up a police station in a town in Brazil after a raid to obtain arms and drugs.
Machine guns and a large cache of confiscated drugs were taken from the building before the explosion.
Globo TV network showed images of the wrecked building with its roof blown off and nearby patrol cars covered in rubble after the attack, which took place in Botucatu around 240km west of Sao Paulo at about 5am on Monday.
Violence by organized crime groups funded by illegal drugs is a major problem in Brazil.
