Andhra Pradesh on 6th May, 2006. Thus, the explanation, is that, the entire incident stated in the written complaint is false and figment of imagination of the petitioner. Whether this version is right or otherwise will be matter for inquiry/investigation. As observed in catena of decisions, there is hardly any option available to the officer in-charge of the police station but to register the FIR under Section 154 of the Code once it discloses commission of a cognizable offence. Indeed, since the named persons in the written compliant were police officials from Andhra Pradesh, it would have been legitimate for the officer in-charge of N.M.Joshi Marg Police Station to conduct preliminary inquiry before registration of FIR. Nowhere in the reply affidavit filed by respondents, in particular respondent No.3, it is stated that such inquiry was conducted by the officer in-charge of N.M.Joshi Marg Police Station. We are conscious of the fact that the respondent No.5 Sub-Divisional Police Officer, Jammalamudugu and SubDivisional Officer, Cuddapah of State of Andhra Pradesh, has stated that an inquiry was conducted by the Officer on Special duty (OSD), Cuddapah to inquire into the allegations and it proved to be baseless. That inquiry done by Officer on Special Duty (OSD), Cuddapah will be of no avail. The inquiry was required to be done by the Officer in-charge of the N.M.Joshi Marg Police Station soon after the receipt of the written complaint
