A private school principal and clerk have been arrested in Patna for allegedly raping a 12-year-old girl and threatening to release a video of the alleged incident, the police said. Police officers said that the girl’s parents came to know about the alleged rape after they took her to the doctor, where she was found to be pregnant. The incident was first reported at the Phulwarisharif police station, but was referred to the women’s police station at Gardanibagh in Patna district. Officials have sealed the school and have sought a report on the functioning of the school from the Block Education Officer. Phulwarisharif police station in-charge Mohammed Qaisar Alam said that the principal and clerk were arrested on Wednesday night. He said the victim’s mother narrated how the 12-year-old was sexually assaulted for six months and was told that she will be killed if she tells her parents about the abuse. A local court has sent the accused to 14 days judicial custody.
