The NYPD says a suspect menaced a police officer with a knife as officers approached three men stripping a car in Brooklyn.

Police say it happened shortly after 4 a.m. Friday on East 19th Street between Glenwood Road and Foster Avenue.

Three officers, including a sergeant, were on patrol in the area when they came upon the trio.

Police say as they approached to arrest them one of the suspects pulled out a knife and threatened the sergeant.

The sergeant discharged his firearm once but it wasn’t clear if anyone was struck. Two of the suspects, including the one with the knife, got away. The third suspect was placed under arrest.

The officers were not injured.

The knife was recovered.
