46-year-old Khan was in Kanpur on August 24 for promotion of his film Bodyguard when activist and ex IIT-ian Omendra Bharat and some others crowded around the Bollywood star's vehicle to present him a Gandhi cap and request him to join their agitation.
However, they were allegedly assaulted by Shera and other security personnel, the complainant has claimed.
DIG (Kanpur) Rajesh Rai said that an FIR has been registered following the order of Chief Metropolitan Magistrate against Khan, Shera and five unidentified persons on a complaint filed by Bharat.
