"Najir Seikh, a bus conductor, was arrested after his mother Ainur Bibi lodged a complaint with the Diamond Harbour police station after rescuing the seven-year-old girl yesterday," Sub-Divisional Police Officer (SDPO) Rupantar Sengupta said.
Ainur Bibi came to know about the incident after Nazir talked about it after returning home in a drunken state, Sengupta said.
Najir and three others had allegedly raped a class-1 student when she had gone outside the school to urinate as the school toilet was closed. She was left unconscious near a bush.
The family members of the girl were unaware of the incident when Ainur Bibi took the girl to the hospital and later reached the police station, Sengupta said.
The family members and other guardians gheraoed the school authorities and demanded the toilet be opened immediately.
