He reiterated that the video of CPI(M) workers 'celebrating' the killing of RSS worker Biju, that he posted on Facebook , was original and not a fake one.

Biju was hacked to death at Payyanur town in Kannur district, which has witnessed a series of clashes between ruling CPI(M) and the RSS for the past one year.
