BROOKLYN (PIX11) -- Another disturbing teen melee broke out inside a Brooklyn McDonald's Friday, and this time, the brawlers turned their violence on an innocent man trying to break the fracas up and on employees of the fast food joint.

The brutality began at the McDonald's on Flatbush Avenue Extension in Downtown Brooklyn at about 3 p.m., just as schools were letting out. In the video, a teen girl can be seen standing on a table taking off her top, apparently preparing herself for the fight.

Two young girls begin trading blows, and people try to tear them apart. An older gentleman in a hat tries to diffuse the situation, but is turned on by the teen boys crowding around, who seemed to have been enjoying the fight. The narrator can be heard gleefully yelling, "Kill him!" interspersed with laughs.

Total chaos breaks out in the restaurant, with teens fighting with cashiers over the counter.

The teens eventually chase the older man outside, with the goon behind the camera screaming, "Kill him right now!" A woman stands in front of him to shield him from the mob. The cameraman shouts, "They can't help you!"

He later posted the video on his Facebook page and sardonically commented, "They put that old man in the hospital I feel bad for telling them to kill him."

911 was called, and a woman was taken to Brooklyn Hospital, officials told PIX11. Another man was aided at the scene, but refused medical attention.

No one was arrested at the scene. Two formal complaints for assault were filed, and are under investigation.

Community activist Tony Herbert is appalled by the video. "These are young people, from the community, that should be doing something more positive."

A Brooklyn mother who frequents the McDonald's location say she's disgusted and scared for her children. "To see something like that ... it's scary."

In March, a similar display broke out inside a Flatbush McDonald's. The video was posted on Facebook and went viral. Six teens ended up being arrested in connection to the incident, with one being charged with felony gang assault.

McDonald's franchise owner Peter LaRose addressed the statement, saying:

"The safety of our customers and crew is our top priority. As the investigation continues, I look forward to working together with the community, our elected officials and the NYPD to address our shared concerns and to ensure that this type of incident can be prevented from happening in our neighborhood in the future.”
