Lawyer Questions NYPD Officer's Brooklyn Rant; Internal Affairs Investigating

NEW YORK (CBSNewYork) -- An NYPD sergeant is under investigation by Internal Affairs after a secretly recorded cell phone video showed him using crude images and language to allegedly threaten a group of young men.

The incident happened on April 28th, inside a Chinese take-out restaurant on Ditmas Avenue in the Kensington section of Brooklyn. Police sources told CBS 2 authorities had to chase the men because of previous noise complaints.

Sgt. Lesly Charles is seen and heard going off on the men.

"I'll take my gun and put it up your [expletive]," the officer is heard saying.

Attorney David Zelman represents two of the men who made the secret video. He said his clients asks the officer "What did I do?"

"The officer doesn't really respond to that question," Zelman told CBS 2's Pablo Guzman.

The young men were told by police to leave, but not before Sgt. Charles rips into them again, pointing a finger at one to shut up and telling the other he lives for work.

"I'm here every [expletive] day, I don't go home. I have no life, no kids," he is heard saying on the video.

Their lawyer said the young men were told to go to Eastern Parkway, where he said they were arrested and released the next day for disorderly conduct.

"Disorderly conduct" has become something of a catch-all type of crime," Zelman said. "I think it's indicative of an overall bigger problem with the NYPD -- that there's really a lack of respect for individuals, their rights and there's a feeling within the NYPD that, hey 'We can do what we want. We run the streets.'"

A police department spokesperson said the young men have filed a complaint with the civilian review board.

Unless there is some kind of settlement, the case could wind up in civil court.
