The gan-rape victim hailing from Bharatpur and studying a medical course moved an "istgasa" (complaint) in the court early this month and an FIR was lodged with Sanganer police station yesterday after the court's order, police said.
The victim has alleged that she was made to drink an intoxicated cold drink, and was later raped by three of her college mates, they said.
The gang-rape accused identified as Vijay Kumar, Yogendra Kumar and Virendra Kumar are yet to be traced, police said.
Preliminary investigation has indicated that the girl was in live-in relationship with one of the accused who promised her to get married, but the boy denied, prompting her to move to the court, they said.
A case has been lodged under various sections of IPC against the three accused, said police.
