executing a bond, with or without sureties, as such officer may
direct, to appear, if and when so required, before a Magistrate
empowered to take cognizance of the offence on a police report,

sufficient evidence or reasonable ground as aforesaid, such
officer shall forward the accused under custody to a Magistrate
empowered to take cognizance of the offence upon a police report
and to try the accused or commit him for trial, or, if the
offence is bailable and the accused is able to give security,
shall take security from him for his appearance before such
Magistrate on a day fixed and for his attendance from day to day
before such Magistrate until otherwise directed.
(2) When the officer in charge of a police station forwards
an accused person to a Magistrate or takes security for his
appearance before such Magistrate under this section, he shall
send to such Magistrate any weapon or other article which it may
be necessary to produce before him, and shall require the
complainant (if any) and so many of the persons who appear to
such officer to be acquainted with the facts and circumstances
of the case as he may think necessary, to execute a bond to
appear before the Magistrate as thereby directed and prosecute
or give evidence (as the case may be) in the matter of the
charge against the accused.
(3) If the Court of the Chief Judicial Magistrate is mentioned
in the bond, such Court shall be held to include any Court to
which such Magistrate may refer the case for inquiry or trial,
provided reasonable notice of such reference is given to such
complainant or persons.
(4) The officer in whose presence the bond is executed shall
deliver a copy thereof to one of the persons who executed it,
and shall then send to the Magistrate the original with his
report.
