Another attack targeting a Jewish man occurred over the weekend in Williamsburg.

The Anti-Defamation League says this is one of two attacks on the Brooklyn Jewish community this weekend.

The ADL is offering a $5,000 reward for any information that may lead to an arrest in the assault Friday night.

The NYPD released video of the attack they say happened Friday around 6:40 p.m.

The video shows a man walk up to the 33-year-old victim dressed in religious clothing and punch him in the back of the head. Police say he yelled "blah" before running down Throop Avenue.

Last Sunday, a 9-year-old dressed in religious clothing was punched multiple times in the face and a faculty member at Columbia University says two swastikas and an ethnic slur were spray painted on a wall outside her office

The regional director of the Anti-Defamation League released a statement saying, "According to our records, this marks the fourth anti-Semitic assault in less the one week, and we are deeply troubled by this."

News 12 is told the victim suffered minor injuries but is expected to be OK.

Police say the incident is being investigated as a hate crime.

Anyone with information is asked to call police.
