A man wearing traditional Jewish garb was shot — possibly with a BB gun — in Brooklyn late Monday, authorities said. 

The 23-year-old victim was walking at Albany Avenue and Montgomery Street in Crown Heights around 10:30 p.m. when someone pulled up in a black van and fired at him, police said. 

He was grazed in the head, and cops believe he was struck by a round from a BB gun. 

He was taken to Maimonides Medical Center with a minor injury, police said. 

The shooter did not make any anti-Semitic statements during the incident, but the NYPD’s Hate Crimes Task Force has been notified, cops said.
