An IO filed filed charge sheet U/sec 173(2) , in which he presented a doctored statement (suppressed & manipulated) to that of the 161 statements of PWs. This act has been done to save an accused from legal punishment. Does this act attracts IPC sec 217 and 218? If so, then sanction from state u/sec 197crpc required to register FIR against the IO (S.I or C.I rank) or not?
First, follow the usual procedure of reporting on deficiencies or manipulation of IO to higher authorities as a complaint and also as grievance and create a record to show that all attempts have been made to bring the attention of Higher authorities on such defective/compromising/connived report. Follow all precautions while complaining against a public servant and approach a court only when you can afford financially and mentally.
