A Muslim man jumped to the aid of three Jewish subway riders after they were attacked by a group of young people who objected to one of the Jews saying "Happy Hanukkah," a spokeswoman for the three said Wednesday.
The New York Police Department's Hate Crimes Task Force is investigating Friday's incident on the Q train.
Friday's altercation on the Q train began when somebody yelled out "Merry Christmas," to which rider Walter Adler responded, "Happy Hanukkah," said Toba Hellerstein.
"Almost immediately, you see the look in this guy's face like I've called his mother something," Adler told CNN affiliate WABC.
Two women who were with a group of 10 rowdy people then began to verbally assault Adler's companions with anti-Semitic language, Hellerstein said.
One member of the group allegedly yelled, "Oh, Hanukkah. That's the day that the Jews killed Jesus," she said.
When Adler tried to intercede, a male member of the group punched him, she said.
Another passenger, Hassan Askari -- a Muslim student from Bangladesh -- came to Adler's aid, and the group began physically and verbally assaulting him, Hellerstein said.
"A Muslim-American saved us when our own people were on the train and didn't do anything," Adler said.
Adler pulled the emergency brake and the train stopped at DeKalb Avenue station, where police came on board.
The 10 suspects, ages 19 to 20, were taken into custody, said Brooklyn district attorney spokesman Sandy Silverstein.
Askari was first handcuffed alongside them, but he was released when Adler told police he was not an attacker, Hellerstein said.
