“As Varsha spent most of her time on the mobile phone, Amutha gave it to the headmistress of her private school a few days ago. She did so to ensure that the girl will focus on studies thereafter,” police said.

The girl, driven by depression, did not speak to anyone in the family and took the extreme step, while being alone on Saturday night.

The shocked family member’s informed Nambiyur police, who arrived and sent the body of the deceased for a post mortem at the government hospital.

A case has been registered and further inquiries are on.
