NEW DELHI: Police on Monday arrested four men accused of drugging and raping an American tourist at a five-star hotel in New Delhi earlier this year.

The incident took place in April and police launched a formal investigation earlier this month after the woman filed a complaint through an American charity.

Victim in her statement informed police earlier that she was part of a tour group visiting India in April when her local guide gave her a spiked bottle of water and raped her with four acquaintances inside her hotel room.

Delhi police spokesman, Dependra Pathak said, "We arrested four of them a few hours ago. And they, as in the tour guide, driver, cleaner and another hotel employee, have been charged with rape".

Sources said the suspects – a tour guide, a driver, a cleaner and a hotel staffer – were questioned for five hours and later taken into custody.

He said the victim, who returned to New Delhi last week, had already recorded her testimony in court and would be able to fly back home in a few days after identifying the suspects. She has told local media in the past week that she had no memory of the assault for nearly three months.
