'Mass rape' video on social media shocks Brazil

The attack happened in a poor community in Rio de Janeiro

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, 16, believes she was doped after going to her boyfriend's house on Saturday and says she woke up in a different house, surrounded by the men.

Arrest warrants have been issued, including one for the boyfriend.

The assault has provoked an online campaign against what campaigners call a culture of rape in Brazil.

Conflicting versions of the story are still coming in, but the rape is said to have taken place in a poor community in western Rio over the weekend.

According to a statement she is reported to have given to police, she woke up on Sunday, naked and wounded, and made her way home.

Only days later did she find out that some of the alleged rapists had put images of the attack on Twitter.

A 40-second-video was widely shared and followed by a wave of misogynistic comments, before the users' accounts were suspended.

In a message posted on Facebook, the victim said she was thankful for the support and added: "I really thought I was going to be badly judged."

She later said: "All of us can go through this one day. It does not hurt the uterus but the soul because there are cruel people not being punished!! Thanks for the support."

'We all cried'

The girl's grandmother told Brazilian media the family watched the video and cried.

"I regretted watching it. When we heard the story we didn't believe what was happening. It's a great affliction. It's a depressing situation," she told Folha de S.Paulo newspaper.

"She is not well. She is very confused. This was very serious."

The attack has shocked Brazil, says the BBC's Julia Carneiro, and campaign groups have been already been calling for protests over the coming days.

There has also been an outpouring of anger on social media, under the hashtag #EstuproNuncaMais (Rape never again).

This tweet reads: "I don't want to live scared of being the next victim anymore, I don't want it"

A collective of journalists posted a satirical image of citizens donning devil's horns, condemning a rape victim for having provoked the attack.

The inscription reads "No to sexism", and the images, clockwise from top right: "But look at her clothes…", "She deserved it!", "16 years old and already has a son…", "Apparently she was on drugs".

The United Nations group UN Women issued a statement calling for authorities to investigate the case, but to respect the victim and not victimise her once more by invading her privacy.

Experts say many cases of rape in Brazil go unreported as victims fear retaliation, shame, and blame for the violence they have suffered.

Media under fire: By Fran Hunter, BBC Monitoring

Brazilian media has come under sharp criticism for their slow reaction to the incident, which was picked up only after news of the video had circulated on social networks.

Beyond that, the shocking incident has sparked an online debate on the "normalisation" of rape in Brazil, and a tendency to blame victims for their suffering, with the hashtag #EstuproNaoECulpaDaVitima (Rape is Not the Victim's Fault) trending prominently.

The debate largely stems from initial comments on the video, which included "she was drunk" and "she was wearing a short skirt".

The media have also been accused of victim-blaming. One of the first articles on the story by media giant O Globo gave prominence to the girl's background and the fact that she was known to be a drug-user.

Brazilian-Mexican actress Giselle Itie was one of thousands to speak out about victim-blaming: "The blame is on the media, who sexualize women in all their products," she said.

"The blame is on the newspaper that makes light of the many rapes that happen…Drunk, drugged, wearing a short skirt, naked, it doesn't matter. It is never the victim's fault."
