New Delhi (CNN) -- Indian police have arrested three men in the gang rape of an American woman who authorities say was attacked after visiting a popular Hindu temple in northern India.
Police announced the arrests Thursday.
All three are in their early 20s, Police Superintendent Vinod Kumar Dhawan said. Evidence collected from a vehicle police seized has been sent to a lab for analysis, he said.
A day earlier, authorities arrested three other men in the case, but the woman said they were not the men who attacked her.
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.
She remains under the protection of a police officer while investigators searched for her attackers.
The woman was unable to provide significant details about the men or the truck they were driving, posing a challenge to investigators, Dhawan said.
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.
