NEW DELHI (Reuters) - Passers-by left a gang-raped Indian student lying unclothed and bleeding in the street for almost an hour, a male friend who was assaulted with her said on Friday in his first public comments on the case that provoked a global outcry. The 23-year-old student died in hospital two weeks after she was attacked on December 16 in a private bus in New Delhi, prompting street protests over the Indian authorities' failure to stem rampant violence against women. The graphic account from the man in a television interview is likely to add fuel to public anger over the death in a country where official statistics show one rape is reported every 20 minutes. The woman's friend told the Zee News television network he was beaten unconscious with a metal bar by her attackers before the pair were thrown off the bus. They lay in the street for 45 minutes before a police van arrived and officers then spent a long time arguing about where to take them, the man said. A court is due to consider the charges on Saturday. The man's comments caused an renewed outpouring of anger on Twitter. "After reading and watching the Zee News interview i'm absolutely shocked and ashamed of being an Indian," said @BarunKiBilli. The man called on the protests to continue, but said he wished people had come to his friend's help when she needed it. You have to help people on the road when they need help. But they switched off the lights of the bus," he said, according to a transcript of the interview.
