Besides Mishra, former municipal chairman Girish Patel and BJP leader Siba Agarwal were booked for allegedly abusing and assaulting DSP J Senapati during the procession on the occasion of Hanuman Jayanti celebrations on Sunday.
He said the case against the three leaders was filed yesterday after the DSP lodged a complaint.
Refuting the allegation, Mishra said filing of the FIR was a surprising development as the SP had thanked him for peaceful conduct of the procession even though several devotees were agitated when police prevented them from holding celebrations at a particular place.
The three men had been booked for wrongful assembly, assault or criminal force to deter public servant from discharging duty, wrongful restraint and obscene act in public.
