“20. From the above discussion it follows that under the scheme of the provisions of Sections 154, 155, 156, 157, 162, 169, 170 and 173 of Cr.P.C. only the earliest or the first information in regard to the commission of a cognizable offence satisfies the requirements of Section 154 Cr.P.C. Thus there can be no second F.I.R. and consequently there can be no fresh investigation on receipt of every subsequent information in respect of the same cognizable offence or the same occurrence or incident giving rise to one or more cognizable offences. On receipt of information about a cognizable offence or an incident giving rise to a cognizable offence or offences and on entering the F.I.R. in the station house diary, the officer in charge of a Police Station has to investigate not merely the cognizable offence reported in the FIR but also other connected offences found to have been committed in the course of the same transaction or the same occurrence and file one or more reports as provided in Section 173 of the Cr.P.C.”
