s 66 Search of place where person sought to be arrested has entered
66.—(1) If any person acting with a warrant of arrest issued under section 58 or acting without a warrant of arrest under section 57 has reason to believe that any person to be arrested has entered into or is within any place, the person residing in or in charge of such place must, on demand of such person acting as aforesaid, allow him or her free entry thereto and afford all reasonable facilities for search therein of the person to be arrested. (2) Where free entry to such place cannot be obtained under subsection (1) it is lawful for a person acting with a warrant of arrest or a provost officer acting without a warrant of arrest, where such warrant is not immediately obtainable in order to enter such place, to break open any outer or inner door or window of any place whether that of the person to be arrested or of any other person if, after notification of his or her authority and purpose and demand of admittance duly made, he or she cannot otherwise obtain admittance.
