A Patna College student, who had written to the University Grants Commission (UGC) complaining about being ragged on the campus, withdrew his complaint on Friday after failing to identify any of his alleged tormentors.

The disciplinary committee of the institution, chaired by principal Bihari Prasad Singh, asked the complainant, first-year political science student Ashutosh Kumar Mishra, to identify who among those on the student rolls had “ragged him”. Unable to identify anyone, Mishra withdrew his complaint.

Singh said: “We gave him a file containing names against photographs of the students and asked him (Mishra) to identify those who had ragged him. But he couldn’t identify anyone.”

In his letter to the UGC, Mishra had said he was so traumatised by the incident in February that he decided to approach the central body rather than the college administration. The UGC wrote to the college asking it to act on the complaint. Mishra was unavailable for comment.
