The 20 persons were identified on the basis of the 12 videos that the Delhi police have with them regarding the February 9 event which was organised to celebrate the martyrdom of Afzal Guru who was convicted for his role in the parliament attack.
The Delhi police is trying to find these persons and have issued look out circulars as well. When questioned, Kanihya Kumar, Anirban Bhattacharya and Umar Khalid denied knowing these persons.
In fact Kumar the JNU student leader told the police that he came to the event late while also adding that he is unaware of who these 20 persons were.
The Delhi police suspect that these persons could well be outsiders who came into the campus on February 9. While looking out for these persons we are also trying to find out who brought them to the campus, a Delhi police official said.
The Delhi police will also call in for questioning another student, Ashutosh soon.
Meanwhile the case will now be handled by the special cell of the Delhi police. Since the probe is expanding and requires a specialised unit this decision was taken.
The Delhi police had indicated two weeks back that they would want to transfer the case to the special cell.
