Indian police said that they have arrested four men on suspicion of raping an American tourist who came to New Delhi alone earlier in 2016, marking another incident of sexual violence to stir outrage

Police Officer Rakesh Kumar said the suspects - a tour guide and his associate, a car driver and a hotel worker - have been arrested. The woman said in her police complaint that the four men raped her after she was drugged in a New Delhi hotel room in April 2016. They denied the accusations. She also said that the four men had shot a video of the attack and had threatened to make it public if she reported the matter to anyone, police said. The woman went back to the United States and registered a complaint through an email to New Delhi's police commissioner. She returned to the Indian capital earlier in December 2016 to pursue the case because she was dissatisfied with the progress of police investigation. The case highlights the persistent violence against women in India despite tougher laws against sexual assault imposed after the December 2012 death of a young woman who was gang-raped on a bus in New Delhi.
