The FIR was registered yesterday on the orders of a local court.
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.
The FIR has been registered under various sections of IPC including Sections 147 (punishment for rioting), 323 (voluntarily causing hurt), 308 (attempt to commit culpable homicide) and 504 (intentional insult with intent to provoke breach of peace).
"The matter will be investigated and action will be taken against anyone found guilty," the DIG said.
Bharat said he along with others activists had gone to meet Khan and request him to join their agitation by offering him a Gandhi cap.
"However, as soon as the actor stepped out of his car, he gestured towards Shera and other security personnel following which they assaulted, pushed and abused me," Bharat alleged.
"We went to lodge an FIR in the Kakadev Police Station. However, the police refused it," he alleged.
He then submitted an application to the city's Chief Metropolitan Magistrate Piyush Pandey on September 5. The court directed the Kakadev police station to lodge the FIR.
