Section 25

If any person acting under a warrant of arrest or any police officer having authority to arrest 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 the place shall, on demand of the person so acting or the police officer, allow him free ingress to the place and afford all reasonable facilities for search in it.

If ingress to that place cannot be obtained under subsection (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 the place and search in it, and in order to effect an entrance into the 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 authority and purpose and demand of admittance duly made he cannot otherwise obtain admittance.
