A person who violates the terms of a restraining order granted in such proceedings must be punished for contempt by a fine of not less than two hundred dollars nor more than one thousand dollars and by imprisonment not less than ninety days nor more than one year. In contempt proceedings arising out of the violation of an injunction granted under the provisions of this chapter, the court or, in vacation, any judge thereof has power to try summarily and punish the party guilty as required by law. The affidavits upon which the attachment for contempt issues are prima facie evidence for the State. At the hearing upon the charge for contempt, evidence may be oral or in the form of affidavits, or both. The defendant shall not necessarily be discharged upon his denial of the fact stated in the moving papers. The clerk of court must, upon the application of either party, issue subpoenas for witnesses and, except as provided in this section, the practice in these contempt proceedings must conform as nearly as possible to the practice in the court of common pleas.
