Some 60 indigenous people set fire to a police station in the northern Brazilian town of Jacareacanga, the government of Para state said Tuesday.
One police officer was slightly wounded by an arrow when the Indians attacked the station Monday night, the state Public Safety Office said.
Members of the Munduruku tribe sacked the station and seized three guns before burning the structure to the ground.
Authorities said the attack was apparently spurred by a judge's decision to release four suspects in the recent murder of a member of the tribe.
An elite state police unit was dispatched to restore order in Jacareacanga, which lies deep in the Amazon jungle nearly 1,700 kilometers (1,056 miles) from Belem, Para's capital. EFE
