A Jewish man wearing traditional religious attire was assaulted by a group of men yelling racial slurs in Williamsburg, cops said Sunday.

The 42-year-old man told police he was walking on Broadway near Lynch Street on Saturday at about 1:15 p.m. when one of the men punched him in the face and made “derogatory racial remark.”

Police sources told The Post one of the men said “You f–king Jew” as they ran away.

The NYPD Hate Crimes Task Force is investigating.

The attack comes just two days after NYPD top brass reported a 67 percent spike in hate crimes this year — 80 percent of which were anti-Semitic incidents.
