Sir, my father was the complainant of his criminal case petition dated 14.11.2018, but FIR registered on 15.11.2021 after direction from Magistrate. My father was never ever interrogated by police even once from 2018 to till date [not interrogated even FIR registration]. Under this situation, we were shocked to find while reviewing the chargesheet that my father's 161(3) statements were created by police by changing the complaint content as per whims and wishes of accused persons. Also, my witness statement was also fabricated one. What would be best course of action under this situation?
