(JTA) — A man fired a BB gun and shouted “Jews, Jews, Jews” at three Jewish teens leaving a synagogue in Baltimore in what police are investigating as a possible hate crime.

One of the pellets from the BB gun struck a window of the Bais Hamedrash and Mesivta of Baltimore, a traditional Orthodox institution located in Baltimore County, in Thursday’s incident.

The gunman, described as being “possibly of Middle Eastern descent,” drove away after firing the gun and shouting at the pedestrians on the first day of Rosh Hashanah.

“We want to stop that. We want to let people know that’s not going to be tolerated in our communities,” Cpl. John Wachter, Baltimore County Police told the local CBS affiliate WJZ.

Baltimore County State’s Attorney Scott Shellenberger told WJZ that if the suspect is caught he could be charged with a hate crime in addition to other criminal acts.
