Rules on Criminal Procedure
Section 20. Increase or reduction of bail. - After the accused is admitted to bail, the court may, upon good cause, either increase or reduce its amount. When increased, the accused may be committed to custody if he does not give bail in the increased amount within a reasonable period. An accused held to answer a criminal charge, who is released without bail upon filing of the complaint or information, may, at any subsequent stage of the proceedings and whenever a strong showing of guilt appears to the court, be required to give bail in the amount fixed, or in lieu thereof, committed to custody.
