NEW YORK (CBSNewYork) — Police on Saturday said they arrested a suspect in connection with an attack on a Good Samaritan who tried to break up a brawl at a Brooklyn McDonald’s.

As CBS2’s Dave Carlin reported, police said Kendale Hamilton, 18, was arrested for gang assault on the 43-year-old man – Iver Whittingham.

Hamilton’s arrest comes on the heels of the arrest of another teen involved in the brawl. Asjaney Naraine, 16, is accused in the assault on a 17-year-old girl that started the melee.

During a chaotic caught-on-video brawl that went viral, Whittingham is seen trying to break up a fight between two teenage girls. But then he himself became a target of violence – punched by a shirtless attacker whom police identified as the just-arrested Hamilton.
