The FIR was lodged yesterday at Colonelganj police station against University Students Union president Dinesh Singh Yadav, its vice-president and two others who had barged into the V-C office to complain against "irregularities" in admissions of research scholars and assaulted some staff members, varsity sources said.
The students on Saturday assaulted the staff members, who prevented them from entering the V-C's chamber, besides vandalising furnitures, they said.
Later in a meeting of senior University officials it was decided that the union Vice-President Shalu Yadav should be suspended and the remaining three be expelled, they said.
Proctor Mata Amber Tiwari suspended Shalu with immediate effect while a file recommending the expulsion of the remaining three has been sent to the V-C for assent, they said.
Meanwhile, additional forces are being deployed around the sprawling University campus following a request from the varsity authorities, police said.
