Among the 21 students who have been asked to explain their behavior at an event at Jawaharlal Nehru University or JNU is Saurabh Sharma, who is a student leader of the BJP, the only ABVP member who is part of the students union at JNU. Mr Sharma told NDTV today that he has received a "show-cause notice" from university officials for violating campus rules by blocking a bus on the night of February 9. "The bus was about to leave with people on board who were outsiders; some of them were armed and had warned they would shoot me. I wanted the police to check their ID cards," Mr Sharma told NDTV.
