The shameful incident took place in Bengaluru on Monday, Oct 5. The girl was abducted when she was on her way back to home from school.
Police arrested the main accused, Krishnamurthy and Mohan. However, investigating cops are yet to nab other accused.
The two boys and other suspects have been booked under Sections 354A (sexual harassment) and 306 (abetment of suicide) of the IPC and under the Protection of Children from Sexual Offences (Pocso) Act.
The girl, whose identity has not been revealed yet, hanged herself from the ceiling fan of her room. In her suicide note, the deceased blamed Krishnamurthy and Mohan.
In the suicide note, she wrote, "Krishnamurthy and Mohan are responsible for my death. These two and their associates took me away when I was returning home from school on Monday."
"They stripped me and clicked my pictures. I have decided to die as I have lost my honour. I and my family need justice. I myself have written this letter and it's my handwriting," she added.
