One person was hit by a bullet and nine buses were burned in a second night of protests by residents of slums here in Brazil's second-largest city, authorities said Tuesday.

Carlos Alberto de Souza Marcolino, 20, was taken to a Rio de Janeiro hospital with a bullet wound in the chest following a shootout involving police.

The protests in Alemao, a complex of shantytowns, were sparked by Sunday's fatal shooting of an elderly woman amid a gunbattle between police and drug gangs.

The toll from Monday night's disturbances in Alemao included four buses burned and damages to a municipal medical center.

Police arrested six people, two of them minors, for their suspected part in the medical center attack.

Other destructive incidents occurred in the "favela," or shantytown, of Chapadao, where five buses were set ablaze in a protest by locals for the death of a 17-year-old man during a police operation.

Violent protests also broke out last week in the tourist district of Copacabana for the death of a 26-year-old dancer who was gunned down during a police raid on the favela of Pavao-Pavaozinho. EFE
