Chennai: A 14-year-old girl was allegedly gang-raped in a private bus by two drivers and a conductor in Tamil Nadu's Salem district, about 350 km from Chennai. The three accused in the case have been arrested. Police say the girl, who had finished Class IX this year, ran away from home in Salem and boarded the bus. She stayed on the bus for the next seven hours as it made several trips from Salem to Omalur. After the last trip, the crew parked the bus in an isolated area and allegedly sexually assaulted the teenager one after the other, police said.
