A statement made by any person to a police officer in the course of an investigation:

Section 162 CrPC provides that a statement made to a police officer in the course of investigation shall not be used for any purpose at any inquiry or trial, except to contradict a prosecution witness in the manner provided by section 145 of the Evidence Act (and, with leave, in re-examination to explain that contradiction). The answer is therefore that it "cannot be used for any purpose except for the purpose of contradicting witness". It is not substantive evidence for or against its maker; section 162(2) separately saves dying declarations and discoveries under section 27 of the Evidence Act.

Current law: BNSS section 181 preserves the corresponding restrictions and exceptions, with cross-references to BSA sections 148, 26(a) and 23(2) proviso. The statement remains distinct from substantive testimony.
