A 'doctored' video allegedly showing arrested JNU student leader Kanhaiya Kumar as raising anti-India slogans has been sent to a forensic laboratory by the District Magistrate conducting a probe into the sedition row.

The video was broadcast by certain news channels. It also went viral on social media and was widely used to condemn the organisers of the controversial event in JNU campus. Later, another set of news channels started broadcasting different version of the same video, questioning its authenticity.

"We got to know about the video showing the JNU student leader raising anti-India slogans and we also came across allegations that the video was doctored. So, we have sent it for forensic examination," sources said.

Refusing to comment on the video clips which the police have probed so far, a senior official claimed that the charges in the case can be established with the help of the footage which the police have in their possession.
