Kolkata: In a shocking incident, a class 10 student of GD Birla School in Kolkata was found dead with her wrist slit and a plastic bag wrapped around her head inside a bathroom on the school premises on Friday afternoon. The body has been sent for postmortem.

In a three-page suicide note recovered from the spot, the student mentioned that she was suffering from depression and had been unable to sleep for the last three months.

Soon after the incident came to light, the Kolkata Police as well as Joint Commissioner of Police Muralidhar Sharma reached the school to examine the scene. They questioned the school authorities and parents as well.

In a statement, Sharma said the student left her classroom around 1.30 pm and entered the washroom. When the teacher, after an hour, noticed the student was missing, a search was started and the body discovered inside the bathroom. “She was rushed to a nearby hospital where she was declared brought dead. We have seized a suicide note and blades. Her face was covered with a plastic sheet. It is too early to comment on the matter. All the seized items were sent for a postmortem examination. We are also examining the CCTV footage,” he said.

A team of forensic experts later also reached the school and collected samples. “The blades were found inside a plastic container, while one of them was lying outside. We are waiting for the postmortem report to ascertain the facts,” said A Reza, a member of the forensic expert team.

A preliminary inquiry has revealed that the girl was a bright student and was preparing for the entrance examination of the Indian Statistical Institute.

Tanmoy Ghosh, spokesperson of a parent’s forum, demanded an in-depth investigation and questioned the alleged lack of security on the school premises. “Why didn’t the school authorities notice that the girl was missing from her classroom for 45 minutes? Where is the security?” he asked.

The victim’s father, a software engineer working in Hyderabad, is scheduled to reach Kolkata on Friday night. The girl lived with her mother.

In 2017, the school was in news after parents staged large-scale protests following allegations that a student had been molested. Following the demonstrations, two physical training teachers of the school were arrested under POCSO Act.
