In a new twist to the Kanhaiya controversy police on Saturday claimed that the video footage of the controversial 9 February JNU event, on which a sedition case was registered against JNUSU President Kanhaiya Kumar and two others, has been found to be "authentic" by the CBI forensic lab. "The CBI lab sent a report to Delhi Police's Special Cell on 8 June saying the raw footage was authentic," a police source said.
