The incident came to light following a complaint by the school administration to a local NGO which took the girl's case to the police. The father of the 16-year-old victim, studying in the eighth standard had taken a loan of Rs. 50,000 sometime ago, the police said.
After the couple could not repay the loan, they asked the creditor to have sexual relations with their teenage daughter in lieu of the repayment of the loan. The accused, Nisar Khan (40), readily accepted the same and enjoyed a sexual relationship with the girl for two years.
The depressed girl, who suffered sexual assault with her mother also a party to it, was totally indifferent in school and after a probe by school teachers, the incident came to light.
Fearing police action, the couple packed off their daughter to Uttar Pradesh from where she was brought back by the police, which nabbed her father and mother, though Khan is still at large.
The police said that the three have been booked under Sections 376, 354, 504 and 506 read with Section 34 of the Indian Penal Code. The girl will be sent for medical examination on Monday, the police said.
