N.Y. Crim. Proc. Law § 410.60
A person who has been taken into custody pursuant to section 410.40 or section 410.50 of this article for violation of a condition of a sentence of probation or a sentence of conditional discharge must forthwith be brought before the court that imposed the sentence. Where a violation of probation petition and report has been filed and the person has not been taken into custody nor has a warrant been issued, an initial court appearance shall occur within ten business days of the court's issuance of a notice to appear. If the court has reasonable cause to believe that such person has violated a condition of the sentence, it may commit such person to the custody of the sheriff , fix bail, release such person under non-monetary conditions or release such person on such person's own recognizance for future appearance at a hearing to be held in accordance with section 410.70 of this article. If the court does not have reasonable cause to believe that such person has violated a condition of the sentence, it must direct that such person be released.
