A 20-year-old woman from Delhi was allegedly raped in a guest house in Hyderabad's Banjara Hills area.
According to Srinivas, Inspector (Banjara Hills), few days back, three friends, two girls and one boy, came to Hyderabad on a vacation.
They were staying in a guest house in Banjara Hills.
They took two rooms - a girl and her boyfriend stayed in one room and the other girl stayed in a separate room.
