Courts may also, on motion of the public prosecutor, order any sheriff or chief of police or the sheriff's or chief's authorized subordinate to arrest and bring before them any person who has been bound by recognizance or summoned to appear and give testimony and who has not attended at the time appointed. When so arrested, the witnesses may be also fined in any sum not exceeding $100 for their neglect, and shall remain in custody until they give their testimony and are discharged from further attendance, or until they give such security as shall satisfy the court, for their appearance to testify.
