Judgment unanimously affirmed. Memorandum: The limited use permitted defense counsel of the police report in this case when he sought to examine prior written statements of the prosecution witnesses for purposes of cross-examination was an error under People v. Rosario ( 9 N.Y.2d 286). We find, however, that there is no reasonable possibility that this error might have contributed to the conviction and that it was, therefore, harmless beyond a reasonable doubt (Chapman v. California, 386 U.S. 18; People v Crimmins, 36 N.Y.2d 230, 237).
