New Delhi, Aug 10 (IANS): A Delhi woman in her 30s was gang-raped in Gurgaon by two of her friends while returning from a party, police said on Wednesday. One of the accused has been arrested.

The incident took place on the night of August 7-8, a police officer told IANS here.

"The woman went to a party in Gurgaon with two friends who started molesting her on their way back to Delhi. When she resisted, they became violent and thrashed her and threw her out of the moving car after which she became unconscious," the women informed police.

The woman was then raped while she was unconscious and dumped along the Delhi-Gurgaon road, the officer said.

The culprits, however, came back, picked her up and took her to a private hospital in Delhi. They then dropped her at her house in Ambedkar Nagar in south Delhi at 4 a.m. on Monday.

They threatened her with dire consequences if she revealed she had been raped.

The woman approached the police on Monday evening. The police arrested one of the accused on Tuesday while the other was absconding.
