A graphic video appears to show a teenager forcibly stripped naked and repeatedly whipped while a group heckled and cursed at him -- all because of a $20 debt.

The video (below) was uploaded to YouTube on Thursday has received almost 40,000 views. And Newark, N.J. authorities are up in arms.

Police are now searching for the victim and assailants in attack, The Star-Ledger reported.

In the disturbing two-minute scene, a man screams, "Where my money at?" at a naked boy on a public street. The hunched-over victim responds, "I don't know," before he is ruthlessly beat with a belt.

For the 90-second whipping, a small crowd laughs, yells obscenities, and tells the victim to say it's a "dog eat dog world" to the camera.

In the end of the video, one of the bystanders reveals that the debt -- apparently owed by the victim's father -- is 20 bucks.

"The perpetrator as well as those who stood idly by laughing and videotaping this act of savage brutality should be brought to justice," said Newark City Council President Anibal Ramos.

Newark Police Director Samuel DeMaio told the Star-Ledger investigators might know where the attack took place.

He also said police know that two Twitter handles were instrumental
in making the video viral.

If caught, the assailants will most likely be charged with aggravated assault.
