Angry crowds have protested after reports that a seven-year-old girl was raped inside a state-run school in the Indian capital.
Delhi police registered a rape case and were questioning teachers and security guards at the school.
Dr Sanjay Kumar, who helped treat the girl, said she had injuries consistent with rape.
Angry mobs gathered at the hospital and threw stones at a nearby bus, shattering its windows. Police cordoned off the road and were trying to disperse the crowd.
Public anger against crimes against women exploded after the fatal gang-rape of a young woman on a New Delhi bus in December.
