The Sabarmati hostel on the JNU campus witnessed violence as a group of masked people armed with sticks and rods barged in attacking students.
Violence broke out at JNU on Sunday night after masked men armed with sticks attacked students and teachers and damaged property on the campus.
The students, who have shut down the entire university for over two months in protest against the hike in hostel fees, have called for a boycott of the exam registration process.
The students, though, are adamant that until all their demands are met, the agitation will continue.
The government has been mediating between the JNU administration and the students union to resolve the crisis.
The semester-end examinations are scheduled from December 12 and the students' union has called for an exam boycott till their demands are met.
Baba Gangnath Marg is closed for vehicular traffic due to students' protest and the long march, the Delhi Traffic Police said.
A general body meeting was held on Wednesday among the students' representatives of various schools and centres where it was decided to boycott academic activities.
The JNU Students' Union has said almost 17 centers have decided to boycott the semester examinations scheduled to start from December 12.
In a press conference addressed by the JNUSU on Thursday, there was no clarity on whether it would call for a boycott of the exams.
The committee scrutinized the estimated utility and service charges in the hostels, which is Rs 2,000 per month (including electricity and water charges of Rs 300).
The details of pending dues from hostel residents were released on November 20 by the assistant registrar of Inter-Hall Administration.
The agitation comes on the first day of the Parliament's Winter Session, which will end on December 13.
Police personnel stopped the students on the Baba Ganganath Marg, around 600 metres from the main gate of the university and some of them were forcefully blocked from moving ahead.
Facing an intense agitation for over two weeks, the JNU administration partially rolled back the hostel fee hike for BPL students not availing any scholarship.
