Section 140.50 - Temporary questioning of persons in public places; search for weapons1. In addition to the authority provided by this article for making an arrest without a warrant, a police officer may stop a person in a public place located within the geographical area of such officer's employment when he reasonably suspects that such person is committing, has committed or is about to commit either (a) a felony or (b) a misdemeanor defined in the penal law, and may demand of him his name, address and an explanation of his conduct.2. Any person who is a peace officer and who provides security services for any court of the unified court system may stop a person in or about the courthouse to which he is assigned when he reasonably suspects that such person is committing, has committed or is about to commit either (a) a felony or (b) a misdemeanor defined in the penal law, and may demand of him his name, address and an explanation of his conduct.3. When upon stopping a person under circumstances prescribed in subdivisions one and two a police officer or court officer, as the case may be, reasonably suspects that he is in danger of physical injury, he may search such person for a deadly weapon or any instrument, article or substance readily capable of causing serious physical injury and of a sort not ordinarily carried in public places by law-abiding persons. If he finds such a weapon or instrument, or any other property possession of which he reasonably believes may constitute the commission of a crime, he may take it and keep it until the completion of the questioning, at which time he shall either return it, if lawfully possessed, or arrest such person.4. In cities with a population of one million or more, information that establishes the personal identity of an individual who has been stopped, questioned and/or frisked by a police officer or peace officer, such as the name, address or social security number of such person, shall not be recorded in a computerized or electronic database if that individual is released without further legal action; provided, however, that this subdivision shall not prohibit police officers or peace officers from including in a computerized or electronic database generic characteristics of an individual, such as race and gender, who has been stopped, questioned and/or frisked by a police officer or peace officer.N.Y.
