"Chapter case" usually refers to a proceeding conducted under Chapter 8 of the Criminal Procedure Code (from Section 106 to Section 124). This Chapter relates to taking bond for keeping peace or good behavior. In your case (though you've not provided full details), PERHAPS, Section 107 may be being applied, which is basically for keeping peace, i.e., to ensure that there is no breach of peace or that public tranquality is not disturbed.
