Police are investigating the act, which allegedly occurred in the municipal school where the girl studied. Sexual assault on females is a hot-button issue in India – the country still is reeling from the horrific allegations against five men and a juvenile who are accused of gang raping and murdering a 23-year-old woman in New Delhi in December.
