The woman has alleged in her complaint that Rampal, Praveen, and Avdhesh, known to her, took her to Palwal on Thursday to show her a plot of land that she wanted to buy, a police official said.
She said the men gave her cold drink which was laced with sedatives and took her to a hotel in Mathura where Rampal and Praveen raped her. They also threatened her of dire consequences, he said.
The woman somehow reached home here after the three left the hotel.
Police has lodged a case in this connection and investigation is underway.
