Investigation

 under  S.173 (8) Cr.P.C. makes it clear that irrespective of report under sub-section (2) forwarded to the Magistrate, if the officer in-charge of the police station obtains further evidence, it is important on his part to forward the same to the Magistrate with a further report with regard to such evidence. The provision also makes it clear that further investigation is permissible, however, reinvestigation is prohibited. The law does not mandate taking of prior permission from the Magistrate for further investigation. Carrying out a further investigation even after filing of the charge-sheet is a statutory right of the police. Reinvestigation without prior permission is prohibited.
