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 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.
