  47.Search of place entered by person sought to be arrested.-
  (1) If any person acting under a warrant of
  
  arrest, or any police officer having authority to arrest, has reason to believe
  
  that the person to be arrested has entered into, or is within, any place, any
  
  person residing in, or being in charge of, such place shall, on demand of such
  
  person acting as aforesaid or such police officer, allow him free ingress
  
  thereto, and afford all reasonable facilities for a search therein.
  (2) If ingress to such place cannot be obtained under sub-section (1), it shall
  
  be lawful in any case for a person acting under a warrant and in any case in
  
  which a warrant may issue, but cannot be obtained without affording the person
  
  to be arrested an opportunity of escape, for a police officer to enter such
  
  place and search therein, and in order to effect an entrance into such place,
  
  to break open any outer or inner door or window of any house or place, whether
  
  that of the person to be arrested or of any other person, if after notification
  
  of his authority and purpose, and demand of admittance duly made, he cannot
  
  otherwise obtain admittance;
  
  Provided that, if any such place is an apartment in the actual occupancy
  
  of a female (not being the person to be arrested) who, according to custom,
  
  does not appear in public, such person or police officer shall, before entering
  
  such apartment, give notice to such female that she is at liberty to withdraw
  
  and shall afford her every reasonable facility for withdrawing, and may then
  
  break open the apartment and enter it.
  (3) Any police officer or other person authorized to make an arrest may break
  
  open any outer or inner door or window of any house or place in order to
  
  liberate himself or any other person who, having lawfully entered for the
  
  purpose of making an arrest, is detained therein.
