The 15-year-old student Mohammed Ismail Hussain was punished and asked to do as many as 100 sit-ups by teachers Mobina Begum and Wahid on September 3, after he was found quarreling with another student on the school premises of Royal Embassy High School at Madannapet area, police said, based on a complaint lodged by the boy's parents.

The boy's parents further alleged that it was only after being forced to do sit-ups by the two teachers, their son developed fever and died today while undergoing treatment.

Based on the complaint, the Madannapet police registered a case under Section 304-A for causing death by negligence, against the two teachers, an investigating officer said.

After the post-mortem report of the boy is out, further action will be initiated, the police officer said, adding that the exact cause of the death, whether it happened due to fever or after being subjected to corporal punishment was still not known.
