An American tourist was allegedly gang-raped by a truck driver and two of his accomplices in the northern Indian state of Himachal Pradesh, local police said Tuesday.
"The 30-year-old was raped by men in a truck on Monday night. They offered her a lift and she accepted it," police inspector Abhimanyu Kumar told AFP.
The incident took place in Manali, a tourist destination 500 kilometres (300 miles) from the capital New Delhi.
Kumar said the medical tests have confirmed that the tourist was raped and police were hunting for the accused men.
"The woman cannot remember the number plate of the truck and she could not understand what the accused were talking about. They drove the truck to an isolated spot and raped her for nearly one hour," he said.
Kumar said every truck driver in Manali had been ordered to report at the local police station as part of the investigation.

The Associated Chambers of Commerce and Industry of India reported earlier this year that female tourist arrivals had fallen after the fatal gang-rape of a 23-year-old Indian student by six men on a bus in New Delhi in December.
