The 15-year-old, who was studying in the government higher secondary school in Kuchaman town, ended life by jumping into a well last night, said police officer Suresh Soni, who is investigating the case.
In her suicide note, she alleged that the principal and two teachers of the school had insluted and harassed her, Soni said.
A case has been registered in this regard, but no one has so far been questioned, he said.
