(b) If a member of the police has reasonable grounds for believing that the attendance of a person is or will be necessary to give evidence or to produce any book, paper or document in criminal proceedings in a magistrate’s court, and hands to that person a written notice calling upon him or her to attend such proceedings on the date and at the time and place specified in the notice, to give evidence or to produce any book, paper or document, likewise specified, that person is for the purposes of this Act deemed to have been duly subpoenaed so to attend such proceedings.
