NEW DELHI: Around 200 students "illegally confined" the top brass of the Jawaharlal Nehru University late on Wednesday night in connection with a case involving a missing student. Najeeb Ahmed , a first year MSc student , allegedly went missing on Saturday following a brawl on the campus the night before. He still remains untraceable.Protesting students allege that the Vice Chancellor acted in an "insensitive" manner on the issue and blocked the administrative department."There is no electricity. The VC, and many other officials are inside and feeling suffocated," said Chintamani Mahapatra, the rector."They have wrongfully confined us since 2.30 pm with unreasonable demand like bring Najeeb immediately. These things are not in our hands but with the police. We are doing whatever we can. We also want safe return of Najeeb. But they (students) have not even listened to our plea. There is a lady official who is unwell and she too is inside," said M Jagadesh Kumar, the Vice Chancellor, while making an appeal to the students in which he also detailed what the administration had done so far on the issue. JNU students' union president Mohit Pandey, however, denied blocking the administrative department. "We have not locked them in. We are lying outside the administrative block and have told them if they want to walk over us and leave, they are free," he said amid slogans. Hundreds of students are lying outside the administrative block.Earlier in the afternoon, Mohit Pandey had said that they had blocked the administrative block because the administration was acting insensitively.Interestingly, some of the demands that the students are making have been already met, said a senior official.“They are asking the JNU administration to make an appeal to Najeeb Ahmed to return to JNU without fear of any victimization. But that was done at around 11.30 am itself and the same was uploaded on the website in the afternoon. Then they are asking why the administration has not lodged an FIR. But the administration had already written to the police multiple times and is in constant touch. Therefore, this is nothing, but illegal confinement and politicizing and communalizing the matter to create unrest in the campus,” the official said.Meanwhile, JNU administration had summoned 12 students to depose before the proctorial committee whose names have been associated with the incidence of violence at Mahi-Mandvi hostel on October 14. The committee has also asked anyone who wants to depose to come forward and help in the investigation. Condemning the students for blocking the administrative block, the JNU Teachers Association has also urged the administration to put more pressure on the police to find Ahmed.The Vice chancellor and other top officials briefed the media for the first time since the disappearance of Najeeb on October 15 noon and said that all necessary measures have been taken to trace him. The authorities are also in touch with the family, the VC said. “We are really concerned about his safety and are constantly in touch with the police, providing them whatever information required. We also appeal to Najeeb if his is reading this to return to the university. We assure him of all help,” said the VC.Accepting the fact that so far no leads have been made on the episode of Ahmed’s disappearance from the campus, the VC added: “Actually nobody knows what has happened to him so far. The family had filed a missing complaint and when we approached the police, we were told that an FIR has already been lodged by the family."
