N.Y. Criminal Procedure Law § 120.80: Warrant of arrest; when and how executed

§ 120.80 Warrant of arrest; when and how executed.

1. A warrant of arrest may be executed on any day of the week and at

any hour of the day or night.

2. Unless encountering physical resistance, flight or other factors

rendering normal procedure impractical, the arresting police officer

must inform the defendant that a warrant for his arrest for the offense

designated therein has been issued. Upon request of the defendant, the

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 defendant upon request as soon after the arrest

as possible.

3. 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.

4. In order to effect the arrest, the police officer may, under

circumstances and in the manner prescribed in this subdivision, enter

any premises in which he reasonably believes the defendant to be

present; provided, however, that where the premises in which the officer

reasonably believes the defendant to be present is the dwelling of a

third party who is not the subject of the arrest warrant, the officer

shall proceed in the manner specified in article 690 of this chapter.

Before such entry, he must give, or make reasonable effort to give,

notice of his authority and purpose to an occupant thereof, unless there

is reasonable cause to believe that the giving of such notice will:

(a) Result in the defendant escaping or attempting to escape; or

(b) Endanger the life or safety of the officer or another person; or

(c) Result in the destruction, damaging or secretion of material

evidence.

5. If the officer is authorized to enter premises without giving

notice of his authority and purpose, or if after giving such notice he

is not admitted, he may enter such premises, and by a breaking if

necessary.
