Any person upon whom such process has been legally served shall appear before such board in obedience to such process and testify as to any matters lawfully pending before such board. If any person upon whom such a subpoena has been served refuses to attend before such board, the clerk of such board, by direction of the board, may issue a capias, directed to some proper officer, to arrest such witness and bring him before the board to testify; and, in case such person refuses to testify, the board shall have the power to adjudge such person to be in contempt and may issue a mittimus, signed by its clerk, and commit such person to a community correctional center for not more than thirty days.
