The second-year student, staying in the university hostel, in her police complaint said the incident took place when she had went out with her boy-friend, who works with an IT firm here, on Saturday night.
When they were walking in the wooded area of the campus, the group of inebriated men attacked them and forcibly took them into deep forest, she alleged in her complaint.
The victim said the gang then demanded money from her boyfriend, who told them that he had kept his wallet in his car. After sending him to bring the wallet along with one of its members, the gang sexually assaulted her.
The victim's boy-friend sighted a beat constable as he was nearing the car and approached him for help following which the gang member accompanying him fled from the scene.
Though he along with police searched for the girl in the area, they could not find her. Around midnight the boy friend got a call from the girl saying the gang had dropped her back near the hostel after raping her.
The complainant was sent to a hospital where she was medically examined, police said, adding that the medical result is awaited. The victim is in stable condition.
