The accused, who is also a research scholar and hails from Patna, is on the run and several teams have been scrambled to nab him.
The incident came to light yesterday when the woman made a call to the PCR yesterday afternoon and reported the matter to police.
The victim was then sent for a medical examination to AIIMS and based on her statement the accused was booked under sections 376 (rape) and 506 (criminal intimidation).
"The girl was friendly with the accused and he came close to her on pretext of marriage. He forced her to develop physical relations with him in her hostel room and his flat in Munirka on various occasions.
"He even filmed the act and threatened her of dire consequences if she reported the matter to police," said a senior police official quoting the victim's complaint.
The victim has also claimed that she had complained about the matter earlier as well but no FIR was filed by the police.
