The Hyderabad police late on Thursday swooped down on a farmhouse in Moinabad in Rangareddy district and foiled a rave party. They arrested some 40 students, including 10 girls. Most of those arrested were students of engineering courses. The police also seized hookahs from the spot. As many as eight semi-clad models from Mumbai and 22 youths were arrested. The farmhouses on the outskirts of Hyderabad are fast becoming havens for such rave parties and obscene dances.
