Hundreds of students staged protests outside the Jawaharlal Nehru University on Monday where the varsity is hosting its third convocation with Vice President M Venkaiah Naidu as chief guest. The protests, which started in the morning, is part of the agitation against the hostel manual and several other issues like restrictions by the administration on entry to the Parthasarathy Rocks, attempts to lock students’ union office, according to the students. They claimed that the manual has provisions for fee hike, curfew timings and dress code restrictions.
