The complaint was lodged by a city-based land broker Shailesh Modi who mentioned his sub-caste as 'Modh-Ghanchi', and alleged that Gohil's remarks are against the members of entire 'Modh Ghanchi' caste.
"Shaktisinh Gohil has made remarks against entire Modh-Ghanchi community for his vested political interest and to target some political person(s)," the complaint said.
The complainant accused Gohil, a former opposition leader in state Legislative Assembly, of playing a caste card to get votes from certain sections of OBC community and of "promoting casteism" and defaming entire 'Modh-Ghanchi' community through his remarks.

The FIR was registered under sections 171 (a) and 153 of IPC for interfering in the exercise of election and promoting enmity between two castes.
Gohil is also charged under section 125 (A) of the Representation of People's Act (RPA) for promoting enmity between two classes in connection with the election and under CrPC section 151 which authorises his arrest by police to prevent any further commission of cognisable offence, the officer said.
Congress and BJP are engaged in an acrimonious exchange over the caste of BJP's Prime Ministerial nominee, who often claims that he was born in a backward class.
Earlier on May 8, Gohil had released a copy of a circular, which he claimed was issued by the Gujarat government, to claim that Modi "manipulated" records to bring his 'Modh Ghanchi' caste into the OBC list after he became chief minister in 2001.
