A gang of rapists who savagely assaulted a woman on a bus in New Delhi last month tried to run her over after the attack which left her fatally injured, reports said on Wednesday, citing a police account of the incident.

Her boyfriend, who was beaten up and thrown off the bus after the woman had been repeatedly raped, managed to pull her to safety just in time, police are set to allege in a 1,000-page charge sheet to be presented in court on Thursday.

The 23-year-old female medical student, whose ordeal has brought simmering anger about widespread sex crime in India to the boil, bit three of her attackers as she attempted to fight them off, local newspapers and TV reports said.
