APPENDIX in 761 THE POWERS OF POLICE TO INVESTIGATE Sec. 154. Information in cognizable cases.—Every information relating to the com- mission of a cognizable offence, if given orally to an officer in charge of a police-station, shall be reduced to writing by him or under his direction, and be read over to the in- formant ; and every such information, whether given, in writing or reduced to writing as aforesaid shall be signed by the person giving it and the substance thereof shall be entered in a book to be kept by such officer in such form as the State Government may prescribe in this behalf. Sec. 155. Information in non- cognizable cases.2—(1) "When information is given to an officer in charge of a police-station of the commission, within the limits of such station, of a non-cognizable offence, he shall enter in a book to be kept as aforesaid the substance of such information and refer the informant to the Magistrate. (2) No police-officer shall investigate a non-cognizable case without the order of a Magistrate of the first or second class having power to try such case or commit the same for trial or of a Presidency Magistrate. (3 Any police-officer receiving such order may exercise the same powers in re- spect of the investigation (except the power to arrest without warrant) as, an officer in charge of a police-station may exercise in a cognizable case. Sec. 156. Investigation, into cognizable cases.—(1) Any officer in charge of a police- station may, without the order of a Magistrate, investigate any cognizable case which a Court having jurisdiction over the local area within the limits of such station would have power to inquire into or try under the provisions of Chapter XV relating to the place of inquiry or trial. (2) No proceeding of a police-officer in any such case shall at any stage be called in question on the ground that the case was one which such officer was not empowered under this section to investigate. (3) Any Magistrate empowered under section 190 may order such an investigation as above-mentioned. Sec. 157. Procedure where cognizable offence suspected.—(1) If, from information received or otherwise, an officer in charge of a police-station has reason to suspect the commission of an offence which he is empowered under section 156 to investigate, he shall forthwith send a report of the same to a Magistrate empowered to take cognizance of such offence upon a police-report, and shall proceed in person, or shall depute one of his subordinate officers not being below such rank as the State Government may by general or special order prescribe in this behalf to proceed, to the spot to investigate the facts and circumstances of the case, and, if necessary, to take measures for the dis- covery and arrest of the offender: Provided as follows : — (a) when any information as to the commission of any such offence is given against any person by name and the case is not of a serious nature, the officer in charge of a police-station need not proceed in person or depute a subordinate officer to make an investigation on the spot; (b) if it appears to the officer in charge- of a police-station that there is no sufficient ground for entering on an investigation, he shall not investigate the case. (2) In each of the cases mentioned in clauses (a) and (b) of the proviso to sub- section (1), the officer in charge of the police-station shall state in his said report his reasons for not fully complying with the requirements o£ that sub-section, and, in the case mentioned in clause (b), such officer shall also forthwith notify to the informant, if any, in such manner as may be prescribed by the State Government, the fact that he will not investigate the case or cause it to be investigated. Sec. 160. Police-officers' power to requite attendance of witnesses.—Any police- officer making an investigation under this Chapter may, by order in writing, require the attendance before himself of any person being within the limits of his own or any adjoining station, who, from the information given or otherwise, appears to be acquainted with the circumstances of the case, and such person shall attend as so required. Sec. 161. Examination of witnesses by Police.—(1) Any police-officer making an investigation under this Chapter (power to investigate) or any police-officer not below- such rank as the State Government may, by general or special order, prescribe in this behalf, acting on the requisition of such officer, may examine orally any person, sup- posed to be acquainted with the facts and circumstances of the case. (2) Such person shall be bound to answer all questions relating to such case put to Kim by such officer, other than questions the answers to which would have a tendency to expose him to a criminal charge or to a penalty or forfeiture. 2.
