Off-Duty Firefighter Jumped by Mob Who Tell Him It's 'Fight Night' Before Brutal Beating

Asking for a little old-fashioned respect can be the prelude to a beatdown in Mayor Bill de Blasio’s New York City.

The New York Post has released video of a Friday night incident in which a rabid mob of teenagers surrounded and then attacked an off-duty firefighter as he walked his dog near his home in the borough of Queens.

Republican mayoral candidate Curtis Sliwa, who founded the civic protection group the Guardian Angels in 1979, posted the video to Twitter.

Warning: The following video contains graphic images and language that some readers will find disturbing.

The 44-year-old victim, whose name was not released by the Post, said he is among those who have objected to the deterioration of his community,  and taken the dangerous stand of telling teenagers to behave as if rules really mattered.

Retribution for preaching civility arrived Friday night.

“There were at least 100 kids … I was walking my dog. They just picked me out and approached me,” the firefighter told the Post in a Saturday interview.

“One kid took his shirt off and said, ‘it’s fight night!’ He said he was 19 and said, ‘I could fight you.’ Everyone took their cell phones out. There were cell phones everywhere,” the victim said.

“They all came at me…A kid came up behind me and hit me in the back of the head with a bottle and I let go of the dog,” he said.

With the dog barking in a fruitless effort to protect its owner, the firefighter was swarmed.

“Give him a shot! Give him a shot! Give him a shot!” one teen repeatedly says on the video.
