Judgment, Supreme Court, New York County (Daniel P. Conviser, J.), rendered November 10, 2015, convicting defendant, after a jury trial, of robbery in the first degree, and sentencing him, as a second violent felony offender, to a term of 11 years, with five years’ postrelease supervision, unanimously affirmed.
Viewed as a whole, including the supplemental instructions, we find that the court’s instructions conveyed the correct standard on the crime of first-degree robbery, including the element of the threatened use of a dangerous instrument (see Penal Law § 160.15 [3]; People v Ladd, 89 NY2d 893, 895-896 [1996]; see also People v Melendez, 242 AD2d 493, 494 [1st Dept 1997]). The court properly explained that display of an instrument alone is not enough, and that display of the instrument must be accompanied by circumstances that convey a threat of immediate use (see People v Pena, 50 NY2d 400, 407 n 2 [1980], cert denied 449 US 1087 [1981]; People v Sharma, 112 AD3d 494, 495 [1st Dept 2013], lv denied 23 NY3d 1025 [2014]).
The positioning of a court officer behind defendant when he testified was minimally intrusive and did not deprive defendant of a fair trial (see People v Gamble, 18 NY3d 386, 397 [2012]). In any event, if there was error involving the court’s decision on courtroom security, it was harmless given the overwhelming evidence of guilt (see People v Clyde, 18 NY3d 145, 153-154 [2011], cert denied 566 US 944 [2012]; People v Lucas, 131 AD3d 875, 876 [1st Dept 2015], lv denied 26 NY3d 1090 [2015]).
We perceive no basis for reducing the sentence.
