A class 4 student of a school in Jharkhand's Dhanbad district was allegedly raped by two school teachers, including the vice-principal, in the sickroom of the institution, police said on Monday.

An FIR was registered at Katras police station in Dhanbad against the two teachers of the Topchanchhi-based school after the girl accused them of raping her a month ago, the police said.

Dhanbad senior superintendent of police Kishor Kaushal told reporters on Sunday that the FIR was lodged a day ago based on the nine-year-old victim's complaint.

'The police are investigating the case from all angles and action will be taken on the basis of medical test report,' the SSP said.

Medical test of the girl was conducted on Sunday at the Patliputra Medical College Hospital, the hospital's superintendent Dr H. K. Singh said.

Police recorded the statement of the girl in a local court after the FIR was registered, the SSP added.

The FIR was lodged against the two teachers, including the vice-principal, and school's sickroom nurse, under different sections of the Indian Penal Code and the POCSO Act.

According to the FIR, the girl had fainted in her classroom a month ago. A teacher sent her to the sickroom, where the nurse gave her medicine, and she lost consciousness. She was allegedly raped there, police said. The vice-principal and the class teacher were involved in the crime, they added.

A few days later, the girl's family took her to a doctor as she was not well. The doctor apprehended some wrongdoing with the girl.

When asked, the girl narrated her ordeal to her parents on Friday.

A team of senior police officers questioned the students, teachers and the principal of school.

The principal of the school, Tanushree Banerjee, said she was not informed about the alleged incident.

'I don't believe it as the school's sickroom remains crowded with students. However, the allegation is serious and the school will cooperate with the police in their investigation,' she said.
