The NYPD's Hate Crime Task Force is investigating an alleged anti-Semitic attack in Brooklyn.

Police say a group of men yelled derogatory remarks at an orthodox Jewish man in Williamsburg on Saturday, and punched him in the face.

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

Last week the NYPD reported a 67 percent increase in hate crimes this year, along with an 82 percent of spike in anti-Semitic incidents.
