Mumbai, Jan 25 (IANS): The National Human Rights Commission (NHRC) has asked the Maharashtra government to explain reports of sexual abuse and mystery deaths of over 500 tribal girls in state-run ashram schools, an official said here on Tuesday.

Taking cognizance of media reports, the NHRC has sent a notice to the state Chief Secretary seeking his detailed report in the serious matter within six weeks.

The NHRC said that the media reports "are indicative of violation of right to life and dignity of the girl students of the schools and also highlights the negligence and apathy of the authorities."

The media has reported last week that the authorities maintained menstruation records of the minor girls and conducted pregnancy tests on them whenever they missed their period or returned from vacations, and this unethical practice was carried out without parental consent.

The matter was exposed when a tribal girl, who came home for Diwali vacation, complained of stomach pains and later she was found to be a victim of sexual abuse at school.

Another 12-year-old girl also alleged similar sexual abuse by a sweeper of the same school in Khamgaon, Buldhana district, which houses 70 girls without a single female superintendent.

According to official figures there are around 1,100 state-run or aided tribal residential schools in Maharashtra catering to 2.3 lakh male and 1.6 lakh female students.

In the past 15 years, over 1,500 students including 700 girls have died and sexual abuse is suspected to be a reason behind these deaths, the NHRC noted.

Frowning at the state government for not taking any initiatives to redress the grievance, the NHRC pointed out that the state has yet to submit a report to the NHRC on its notice of October 10, 2016 on allegations of deaths of 740 tribal students in ashram schools, despite a reminder on November 26.
