Teen allegedly knocked out during arrest, caught on camera

CLINTON HILL (WABC) -- New video has surfaced of an especially harsh arrest by police on the streets of New York City.

So, did police go too far?

"It's just a cigarette!" Marcel Hamer is heard saying in the video.

The video begins with Marcel Hamer already on the ground but still struggling with the plainclothes cops trying to arrest him on suspicion of smoking pot.

"Mister it's just a cigarette sir!" Marcel Hamer said in the video.

And then, you can't see it but you sure can hear what sounds like contact with Hamer's head. Enough to lay him out cold on that Clinton Hill corner.

"He knocked out! Yes, he knocked out! You knocked him out!" people are heard saying in the video.

Four months later, attorneys for Hamer filed a notice of claim against the city for $5 million. They claim the now 17-year-old is a victim of excessive force.

"He's been complaining of headaches, he's been repeating a lot of things, he's different," said Mary Hamer, Marcel's mother.

It's the second piece of video to emerge just Tuesday involving dramatic arrests in Brooklyn. Another clip, from nearby Bedford-Stuyvesant, shows two officers punching a different drug suspect, who'd led them on a chase.

"I see these videos as another piece of information we need to use to improve the relationship between police and community and in many cases to heal the relationship between police and community," Mayor de Blasio said.

The police department already suspended one of those officers, from the 79th Precinct; the other for now is off the street.

This time, it's cops from the 88th Precinct who are under the microscope.

The NYPD will say only that it's referred the case to internal affairs.
