The accused, a fourth grade employee at the government school, has been arrested, they said.
The incident took place around 11 AM when the girl, a class third student, was leaving for home after appearing in an examination. The victim realised that she had forgotten her stationery items in the classroom and returned to collect it, police said.
Meanwhile, the accused stopped her and took her to a gallery inside the school premises where he allegedly raped her.
Meanwhile, the victim's parents have alleged the school principal and teachers of "sheltering" the accused.
