New Delhi, Jan 17 (UNI) In response to the statement by Delhi Assembly Speaker Vijender Gupta, Punjab Chief Minister Bhagwant Singh Mann said on Saturday that the BJP government in Delhi is free to demand a CBI probe into the issue of the forensic report over the alleged remarks by AAP leader Atishi in the Delhi Assembly. Mann pointed out that forensic investigation has already established that Delhi Assembly Leader of Opposition (LoP) Atishi did not say any such thing which insults the Sikh gurus. He accused the BJP of adding subtitles to the video, which, he said, was the real insult.
