A Class IX student was allegedly raped by one of her classmates, while three others videographed the act in the Nayagarh district of Odisha, the police said here on Monday. The parents of the victim lodged an FIR with the Sarankul police station in the district after the video went viral. The heinous act was carried out a month ago in the Sarankul village, when the victim and the accused were attending a tuition class. After the matter came to the fore, it was proposed in a village meeting that the prime accused and the girl should be married. However, the family of the accused rejected the proposal. Police said they had arrested the minor boy while his three friends were absconding.“It is a very sensitive matter and we are investigating it on a top priority basis,” said Kanwar Vishal Singh, Nayagarh Superintendent of Police.
