A vicious brawl at a McDonald's on Flatbush Avenue in Brooklyn Saturday is under investigation by the NYPD. Graphic cell phone video of the fight shows one adolescent girl fighting against four others for several minutes until she's knocked to the floor and kicked repeatedly. A large crowd cheers, but no one does much to intervene until an adult is seen trying to stop the kicking. "Yo, she’s dead," one young bystander observes.

An NYPD spokesman tells us the incident is being investigated as an assault. "We are aware of the individuals," the spokesman said, adding that no one was hospitalized as a result of the fight. This particular McDonald's is located in the 70th Precinct on Flatbush Avenue near Beverly Road, not far from Erasmus High School.

Anyone with information about the McDonald's fight is asked to call Crime Stoppers at 1-800-577-TIPS.
