Patna, Aug 4 - Patna College authorities Tuesday began a probe into the alleged ragging of a student in the premises of the institution. Police have lodged a case and arrested the accused, officials said.

BA student Vikas Kumar had allegedly ragged his junior Ashutosh Kumar Ranjan Monday. After the incident came to light, college principal L.K.P. Singh had ordered the anti-ragging committee to hold an inquiry and submit a report within two days.

'The committee began its probe into the incident today,' a college official said.

Patna Deputy Superintendent of Police Sheila Irani said Kumar was arrested from Minto Hostel in the college premises after Ranjan filed a complaint.

Ranjan told the police that he was assaulted after he refused to obey an order by Kumar and his friends to strip and perform a funny act.

S.A. Hashmi, officer in-charge of Pirbahore police station, said a case had been registered against Kumar and four other students.

Patna University proctor Ras Bihari Prasad Singh has also sought a report from the college regarding the alleged incident of ragging.
