New Delhi ( CNN ) -- An American woman who authorities say was gang-raped by three men after visiting a popular Hindu temple in northern India was resting in her hotel Wednesday under the protection of a police officer while investigators searched for her attackers . The 31-year-old woman was raped after leaving the Vashishth Temple site around 1 a.m. Tuesday , according to police . After failing to find a taxi to take her back to her hotel , she accepted a ride from three men who took her to a wooded area where they raped and robbed her , authorities said . The woman was examined at a hospital and released , according to police Superintendent Vinod Kumar Dhawan . She was staying at a hotel in Manali with friends , according to authorities . A police escort has been assigned to protect her , they said . The woman was unable to provide significant details about the men or the truck they were driving , making it difficult for police to make an arrest , Dhawan said . Regardless , a special investigative team had been formed and had been carrying out raids at potential hideouts , Dhawan said . Authorities had arrested three men in the case , but the woman said they were not the men who attacked her , according to police . It was unclear if the men , who had been questioned to gain possible leads , remained in custody Wednesday . A spokesman for the U.S. Embassy in New Delhi confirmed diplomatic officials had been in touch with local authorities about the case , but declined to talk further about it . Violent rapes in India have made headlines recently . A 4-year-old girl died after being sexually assaulted by a 35-year-old man in Ghansaur in April , and a 5-year-old girl was allegedly raped two weeks earlier in New Delhi . Two men were arrested in that case . Six men are facing rape and burglary charges after the rape of a Swiss tourist in March . And a 23-year-old woman was gang-raped on a bus in New Delhi in December and later died of her injuries . Five men were charged in the case ; one has since died in prison . That attack spurred protests across the nation , where most women have stories of sexual harassment and abuse on public transportation or on the streets , according to the Indian Council on Global Relations .
