College Street: The University Grants Commission has asked Calcutta University to conduct a fresh probe into the ragging complaint lodged by a first-year law student, three days after the university said its probe team had found no merit in the allegation.

"The university will start a fresh investigation. The UGC's anti-ragging cell has told us that they are not accepting our report. We have to abide by the UGC directive," registrar Rajagopal Dhar Chakroborti said.

"We will discuss the matter with vice-chancellor Sonali Chakravarti Banerjee on Monday and decide when to start the probe."

The UGC's directive followed a mail from the student's mother alleging that the university's inquiry committee had not bothered to find out how the student suffered a cut on the head or why his elder brother had to call the police helpline with the plea that he be rescued from a hostel room.

The student has alleged that a few seniors at New Law College Hostel, on Bidhan Sarani, had confined him in a second-floor room and severely assaulted him on the night of December 7. Following a text alert from him, his brother called up 100 - the police helpline.

Police sources had told Metro that a team from Amherst Street police station rushed to the hostel after the call and rescued the student from a room.

Following the university's claim on December 13 that it had found no evidence of ragging, the student's mother emailed to the UGC's anti-ragging cell copies of her son's medical reports, a photograph of the cut on his scalp and the FIR he had lodged.

A UGC official called up the mother on Saturday and wanted to know whether she was satisfied with the findings of the university's inquiry. "I told her that my son had not got justice," the mother said.

The UGC then ordered a fresh probe. It's directive has been conveyed to the university through email and over the phone, the registrar said.

Education minister Partha Chatterjee had on Friday called for a "fair probe" into the ragging complaint.
