Brazilian police are hunting more than 30 men suspected of raping a teenage girl in Rio de Janeiro, and of putting video of the attack on social media.
The girl is reported to have gone to her boyfriend’s house on Saturday and to have regained consciousness later, surrounded by the men.
The assault has provoked an online campaign against what campaigners call a culture of rape in Brazil.
A 40-second-video was widely shared and followed by a wave of misogynous comments, before the users’ accounts were suspended.
The united nations group un women issued a statement calling for authorities to investigate the case, but to respect the victim and not victimize her once more by invading her privacy.
