If any person to whom a summons is issued under the preceding section or section forty-two or fifty-five fails to appear in response to such summons, the court issuing the summons may issue a capias to compel the attendance of such person, and such capias shall be issued and served in the same manner as a capias to compel the attendance of witnesses who have failed to appear on a subpoena issued in behalf of the commonwealth in a criminal case.
