A 19-year-old woman from Nepal was raped by four men, of which three have been arrested, police said Wednesday.
One of the accused was known to the victim and took her to an isolated place in south Delhi's Vasant Kunj area Tuesday evening.
The woman was raped in turns by the man she knew and his friends, who threatened her with dire consequences if she told anyone about the incident.
The woman called the police and informed them about the assault. The man she knew is on the run.
Police said Ankit Bhargava, 26, was nabbed from the spot, while two others - Sandeep, 25 and Ashish, 20 - were arrested later from the same area.
All the accused are unemployed.
Police said the man who was known to the woman had assured her of a job as domestic help somewhere.
