Section 42, 43 of Code of Criminal Procedure – 
42. Arrest on refusal to give name and residence.—(1) When any person who, in the presence of a police officer, has committed or has been accused of committing a non-cognizable offence refuses, on demand of such officer, to give his name and residence or gives a name or residence which such officer has reason to believe to be false, he may be arrested by such officer in order that his name or residence may be ascertained. (2) When the true name and residence of such person have been ascertained, he shall be released on his executing a bond, with or without sureties, to appear before a Magistrate if so required: Provided that, if such person is not resident in India, the bond shall be secured by a surety or sureties resident in India. (3) Should the true name and residence of such person not be ascertained within twenty-four hours from the time of arrest or should he fail to execute the bond, or, if so required, to furnish sufficient sureties, he shall forthwith be forwarded to the nearest Magistrate having jurisdiction. 43. Arrest by private person and procedure on such arrest.—(1) Any private person may arrest or cause to be arrested any person who in his presence commits a non-bailable and cognizable offence, or any proclaimed offender, and, without unnecessary delay, shall make over or cause to be made over any person so arrested to a police officer, or, in the absence of a police officer, take such person or cause him to be taken in custody to the nearest police station. (2) If there is reason to believe that such person comes under the provisions of section 41, a police officer shall re-arrest him. (3) If there is reason to believe that he has committed a non-cognizable offence, and he refuses on the demand of a police officer to give his name and residence, or gives a name or residence which such officer has reason to believe to be false, he shall be dealt with under the provisions of section 42; but if there is no sufficient reason to believe that he has committed any offence, he shall be at once released.
