A new video has reportedly surfaced showing some "outsiders" allegedly shouting anti-India slogans at the event organised at Jawaharlal Nehru University (JNU) on Feb. 9 against the hanging of Afzal Guru, who was convicted in the 2001 Parliament attack case. The Delhi Police is examining the video to confirm its authenticity.

JNU student Umar Khalid, who on Tuesday night surrendered before the Delhi Police in connection with the incident, has also been spotted in the video, but was apparently not involved in anti-India sloganeering, Press Trust of India reports.

Photographs of eight persons suspected to be outsiders have been shortlisted for further investigation, police said. The identification of these people is yet to be established.

The video surfaced hours after the Delhi Police, in its report to the Delhi High Court, claimed the presence of some "foreign elements" at the event at JNU.

The Delhi Police have begun further investigation into the incident with the interrogation of Khalid and Anirban Bhattacharya, who also surrendered along with Khalid. Both the JNU students told the police that they spoke in favour of Guru at the event, according to India Today.  

They also told the police that they did not shout anti-India slogans.

Khalid and Bhattacharya, along with other JNU students Rama Naga, Ashutosh Kumar and Anant Prakash, disappreared after JNU students leader Kanhaiya Kumar's arrest on Feb. 12. They returned to the campus Sunday and agreed to surrender after the High Court approved their request of surrendering at a place of their choice.

Kanhaiya was sent to the police remand until his bail plea, the hearing for which was initially scheduled for Wednesday, will be heard on Feb. 29. These JNU students have been charged with sedition for anti-India sloganeering at the Feb. 9 event, organised to reportedly protest against the "judicial killing" of Guru.

Several footages aired by national news channels showed that anti-India slogans were raised at the event. However, some other videos reportedly showed Kanhaiya shouting slogans seeking freedom from poverty, Brahmanism, feudalism and capitalism.

The issue also rocked Parliament, which assembled on Wednesday for the Budget session.
