Police in Rio de Janeiro say they’ve detained several of their own officers for an incident in which police apparently fired at a car and killed five young men. Local news media say the dead were aged 16 to 25 and included two brothers. The O Dia newspaper says the men from the Morro da Lagartixa slum were out celebrating the 16-year-old’s first paycheck. Rio police say an unidentified number of police have been taken into custody following Sunday’s shooting. They could face criminal charges and could also be removed from the force.
