Appeal from a judgment of the County Court of Tompkins County, rendered February 9, 1976, upon a verdict convicting defendant of the crimes of criminal possession of a controlled substance in the fifth degree and criminal possession of a controlled substance in the sixth degree. The judgment was rendered following a trial by the court without a jury and the defendant was sentenced as a second felony offender to an indeterminate term of imprisonment of not less than three years nor more than six years. On this appeal the defendant urges reversal of the conviction and dismissal of the indictment based upon his argument that a search warrant was improperly issued herein, and that even if valid, the warrant was illegally executed in seizing contraband outside the apartment described in the warrant. It is also contended that it was error to hold that the facts of the present case are sufficient to sustain a warrantless search as an incident to the arrest of the defendant. It is clear that probable cause existed for issuance of the warrant. The facts concerning defendant’s involvement in the possession and sale of narcotics, as contained in an affidavit submitted by an investigator with the State Police, were obtained from a confidential informant. The informant was identified and personally examined by the court, and the warrant was issued only after the court was satisfied of the reliability of the informant (People v Montague, 19 NY2d 121).

The only access to the apartment was an outside metal stairway resembling a fire escape. While the police were in the vicinity of the bottom of the stairway, they then observed the defendant and his companion leave the apartment and start down the stairway. When his companion had reached the bottom of the stairway and the defendant was about half way down the police officers identified themselves and ordered them to stop and stay where they were. Thereupon the police observed the defendant sit down on the step immediately behind and above the one on which he was standing; that he had a brown paper bag in his right hand and that as he sat down he moved his hands to the side and to the rear of his body. One of the police officers then observed a bag fall from where the defendant was sitting on the stairway to the ground directly underneath it. Nothing was observed on the stairway prior to the time the defendant sat down. There was also testimony to the effect that the defendant was ordered by the police to come down off the stairway; that they
