Accused Dileep Sarkar, a native of Kolkata, who runs a hotel here, allegedly raped the 15-year-old girl on at least five occasions resulting in her getting pregnant, Madhapur inspector K Narsimhulu said.
"The accused is claiming that he paid money to the girl to have physical relation with her," the Inspector said.
The minor girl had delivered a baby girl in her school's toilet at Madhapur in November last year.
A case under section 376 of IPC and under relevant sections of POCSO Act has been booked against the accused.
The victim and her baby have been sent to the state home at Yousufguda here.
