Three male teenagers approached the 24-year-old victim at the intersection of Albany Avenue and Union Street at about 11:40 p.m., according to police and sources. One of the teens then struck the man in the face, knocking him to the sidewalk, police and sources said.
The man was taken to Methodist Hospital in stable condition, a police spokesman said.
There were no immediate arrests and the investigation was ongoing.
Local Jewish leaders spoke out against the attack.
“The greatest civil right is to be able to walk around — that’s how we live our lives," Eli Cohen, the executive director of the Crown Heights Jewish Community Council, told DNAinfo New York.
"All of us should expect that, whether we’re Jewish, black, white, yellow — you know, it makes no difference. We’re entitled to expect to be able to walk down the street without being assaulted.”
