The NYPD's hate crime division is investigating an attack on a Jewish couple on the Upper East Side.
Witnesses say it started when at least five cars and two motorcycles, some flying the Palestinian flag were making a ruckus blocking traffic briefly on 2nd Avenue.
Then the vehicles turned onto 63rd and stopped—and a group of people got out and confronted the victims, a Jewish couple, in front of their building.
They say some were waving Palestinian flags.
Police say they yelled anti-Semitic slurs at a 27-year-old man walking with his wife.
They hit her with a water bottle and punched him in the head, cutting his ear.
NY1 spoke with people who live in the couple's building.
"I live here for 18 years. It never happened before. I'm Jewish and I'm worried," one area resident said.
"It's always a sad situation when we're fighting with each other over things that are, at the time, meaningless," another said.
"It's immaturity and stupidity, in my opinion. It's unnecessary," said a third.
"You would not think that, living in the heart of Manhattan, something like this could ever occur. I was a child during World War II...and I never thought that I would in my life think that it could happen again and here I am, and it it's almost like the beginning," another neighbor said.
Witnesses say the man recorded some of the incident on his cellphone, and even caught the license plates of some of the cars.
So far no arrests have been made.
