Delhi Police's Special Cell have questioned a few staff members and students in the last few days in connection with the February 9 event over which a case of sedition was registered and the varsity's students union president Kanhaiya Kumar and two others were arrested.
The questioning was a part of investigation and none of them were detained. The students were identified with the help of the video clip of the event which was declared authentic by the CBI forensic lab, a senior official said today.
Among others who were questioned were the ones who had initially sanctioned permission for the event and given it clearance. The questionings were conducted in the past two weeks.
The Special Cell also wrote a series of letters to JNU authorities asking them to cooperate in the investigation, the official added.
The raw video footage of the controversial February 9 JNU event was to be "authentic" by the CBI forensic lab earlier this month.
Earlier, Delhi Police had sent four video clips of the event to Gandhinagar-based Central Forensic Science Laboratory (CFSL) which in its report, in May, had said that they were genuine.
However, a Delhi government-ordered probe, into a set of seven video clippings of the controversial event sent to the Hyderabad-based Truth Labs, had found two clips to be manipulated while others as genuine.
Kanhaiya, Umar Khalid and Anirban Bhattacharya were arrested in February and later granted bail in the case, which is now being probed by Delhi Police's anti-terrorism unit Special Cell.
