An FIR was filed against five men on Saturday for allegedly gangraping a US woman at a five-star hotel in Connaught Place in Delhi.
The FIR is based on a complaint filed by an NGO through an email.
The complaint said that five men had entered the woman's room on the pretext of some tour and travel-related work and raped her.
The victim did not approach police as she was scared and returned to the US. The accused also threatened her of dire consequences if she told anybody about it, the complaint said.
"An FIR was today registered in connection with the incident," Delhi Police spokesperson and Joint Commissioner of Police (South West) Dependra Pathak said.
