After initial inquiry and on the basis of a complaint lodged by the girl's father Lal Chand today, an FIR has been lodged against the school management, Circle Officer Rakesh Yadav said.
The girl had allegedly received a blow on her nose during Karate training on Wednesday and was rushed to a hospital but could not be saved.
She died of excessive bleeding.
No complaint was registered after her death so the post-mortem could not be done, the officer said, adding that the police will not investigate on the basis of the medical report.
