New York City police are investigating the assault on a 25-year-old Lubavitcher Chosid man in Brooklyn.

Police say the victim was walking in Crown Heights when he was stabbed in the back as was reported by YWN Wednesday. They say when he turned around he saw a man running away from him.

Chief of Detectives Robert Boyce tells WINS-AM that police are looking at the incident as a possible hate crime.

The Anti-Defamation League is offering a $5,000 reward for information leading to an arrest.

The victim suffered a collapsed lung.

There were no words exchanged between the victim and the attacker. It appears to be an unprovoked attack.

Just three months ago, a Hatzolah member was stabbed in an unprovoked attack on Eastern Parkway. The attacker was never apprehended.
