The NYPD is investigating a series of bias incidents in Brooklyn.

WABC-TV says all eight incidents have targeted Jews.

The NYPD says thye occurred in Crown Heights and ranged from acts of vandalism to violence.

The most recent occurred Sunday night. A surveillance video shows a group of men punching a 20-year-old man in the face.

Last Wednesday, a 12-year-old boy was punched and knocked to the ground.

Anti-Semitic graffiti also was spray-painted around the neighborhood.

Rabbi Yaacov Behrman of the Jewish Future Alliance tells WABC that he wants to see increased police patrols.
