A six-year-old girl was allegedly raped in an upscale school in Bangalore two weeks ago, triggering fierce protests by parents on Thursday.
While some reports said the girl was raped by "unknown persons", others pointed to the involvement of two staff members.
"A six-year-old girl student was allegedly raped by unknown persons in Vibgyor High School under Varthur police station limits, which came to light on July 15 (Tuesday)," PTI quoted KV Sharat Chandra, joint commissioner of police (Law and Order - East), as saying.
He added the girl was sent for medical examination and the report was awaited. The crime is reported to have occurred on July 2.
Human resource development minister Smriti Irani asked the ministry secretary to look into the alleged rape, an NDTV tweet said.
The incident comes at a time when the nation is reeling under a series of sex crimes and a section of politicians has courted controversies by coming up with several explanations for the spate of such cases.
Chandra said an investigation into the Bangalore school incident was underway and there were no arrests so far. The police officer confirmed that parents had alleged the involvement of school staffers.
Meanwhile, hundreds of parents stormed the institute on Thursday, demanding answers from the school authorities and accusing them of being "insensitive".
Parents tried to force their way into the building as police tried to pacify them. Window glasses were broken in the melee.
Some reports said in the wake of the incident, many top schools in the Karnataka capital had asked parents to sign a form that the authorities were not responsible for the safety of students during special events including field trips and excursions, adding fuel to the already simmering protests over the Class 1 student's plight.
Faced with protests, Rustom Kerawala, spokesperson of Vibgyor High School, said, "If somebody is found guilty of raping, let him be hanged."
He added the school management was co-operating with the investigators. "We are waiting for the final conclusion from authorities."
Kerawala also assured that security measures will be stepped up in the school, as "safety of the child is paramount".
CPI(M) leader Brinda Karat condemned the incident and said, " It's a horrendous and condemnable act."
Highlighting the recurrent sex crime cases that have been grabbing the headlines, she added, "These things have become worrisome and the concern for women's safety continues."
