Both of them had food in a five star hotel Thursday night from where he drove her to an isolated place and allegedly raped her in the car after offering her a drink laced with some drugs. He then left her in front of the hotel where she was staying.
The woman managed to reach a police car near the Jawahar Circle area in the city and lodged a complaint. The man was arrested within three hours.
"We have registered a case and are interrogating him," Singh said.
