A 15-year-old schoolgirl was raped allegedly by four to five people, including her classmate and a taxi-driver, in Shimla on Tuesday. The classmate and the taxi driver were reportedly known to the girl's family and have been taken into custody by the police, while the other accused men are missing. The teenager, who had been missing from her house for the past three days, was found in a semi-conscious state near her house in Vikas Nagar, a suburb of Shimla on Tuesday night.
