Video: 5 thugs repeatedly stomp, punch boy, 15, on busy NYC street — and steal his sneakers. Crime expert says there's 'basically nothing you can do to these kids.'

Cellphone video caught the moment when a group of five boys repeatedly stomped and punched a 15-year-old boy on a busy Manhattan street Monday before stealing the victim's sneakers and running off unscathed.

A crime expert told the New York Post in response to the vicious beatdown that there's "basically nothing you can do to these kids.”

What are the details?

The brutal assault occurred near the corner of Amsterdam Avenue and West 188th Street around 2:25 p.m., police told the Post.

The victim appeared to be on his back on the sidewalk and up against the wall of a building when the gang of thugs beat him up.

Apparently a passing motorist recorded video of the attack, and someone is heard remarking from inside a vehicle, "They f***in' this kid up, bro. Stealin' his s**t. Damn, they taking his shoes, bro!"

The same person adds, "That's some f***ed up s**t, bro."

The attackers then run to the corner and enter a parked black sedan before taking off. Another teenager then walks over and checks on the victim, the Post reported.

Police told the Post the crime was reported to them.

“It was reported to police that a 15-year-old was assaulted by a group of individuals who forcefully removed his property,” police said in a statement, the paper said. “The victim sustained injuries to his face and body.”

'Basically nothing you can do to these kids'

Joseph Giacalone — a former New York City police sergeant who is a professor at City University of New York’s John Jay College of Criminal Justice — told the Post there's little that can be done to the attackers amid our present criminal justice climate.

“Here’s the problem with this one," Giacalone told the paper. "You have a gang assault — which is a bail-eligible offense — and you have kids that are under the age of 18. So there is just basically nothing you can do to these kids.”
