Footage showing two teenagers being shot in Brazil has emerged, amid claims police did nothing to stop the killings.
The video shows the victims' final moments and also captures a police car nearby, which later drives off - apparently ignoring the shooting.
Eight officers have now been arrested.
From Rio de Janeiro, the BBC's Julia Carneiro reports.
