2006 New York Code - Warrant Of Arrest; When And How Executed.

 
    §  153-a.  Warrant  of arrest; when and how executed. (a) A warrant of
  arrest may be executed on any day of the week, and at any  hour  of  the
  day or night.
    (b)  Unless  encountering physical resistance, flight or other factors
  rendering normal procedure impractical,  the  arresting  police  officer
  must  inform the subject named therein that a warrant for his arrest for
  attendance at the proceeding designated therein has  been  issued.  Upon
  request of such subject, the police officer must show him the warrant if
  he  has  it  in his possession. The officer need not have the warrant in
  his possession, and, if he has not, he must show it to the subject  upon
  request as soon after the arrest as possible.
    (c)  In  order  to  effect the arrest, the police officer may use such
  physical force as is justifiable pursuant to section 35.30 of the  penal
  law.
    (d)  In  order  to effect the arrest, the police officer may enter any
  premises in which he reasonably believes the subject named therein to be
  present. Before such entry, he must give, or make reasonable  effort  to
  give, notice of his authority and purpose to an occupant thereof.
    (e)  If the officer, after giving such notice, is not admitted, he may
  enter such premises, and by a breaking if necessary.
