Daisy Rathore, 12, who hanged herself from a ceiling fan at her home on December 1, ensured that her tormentor was punished, as she wrote the teacher's name on her palms and hands and also the reason for her extreme step.
"We are waiting for the autopsy report and recording statements of victim's friends and classmates. We will take strict action against the culprit," Joint Commissioner of Police Madhup Tiwari told IANS on Thursday.
"On her palms and hands she wrote that she did not want to go to school anymore. She apologised to her mother and grandmother and said she was going to meet Lord Krishna," he added.
Around 4 p.m., when the mother returned, she discovered her daughter's lifeless body, a police officer said. A suicide note was also recovered.
"She had cried in the school bathroom following the episode," Kamal Rathore told IANS.
"She had been insisting that I change her school but I did not know the extent of the crisis. I had not realised how extreme it has been and that she would commit suicide," she said.
"Her science teacher used to rebuke her on trivial issues," the mother added.
The mother broke down before a few reporters on Thursday as she narrated the incident.
"I was planning to take her out on her birthday this December 20. But now she has left us. I should have changed her school."
Kamal Rathore has been a single mother, since her husband passed away some eight years ago.
Apparently, the tormented student had told some of her friends that she would commit suicide and would not meet them again.
The school management has set up an internal committee to probe the incident and will submit its report to the Delhi Police.
