EAST HARLEM – Disturbing video posted on Facebook over the weekend shows a group of teens snickering as they torture a delivery man.

The assault happened at the Wagner Houses, according to the description and comments on the initial Facebook post.

Video shows the delivery man, clutching several bags of food, walk out of the lobby just before a teen blindsides him, knocking him to the ground.

The assault appeared to have been planned, as the person filming yells “World Star” before the shove, referring to the website infamous for knockout videos and other disturbing content.

“What’s up with you bro?” the teen says to the delivery man, as the others yell “Push him, push him!”

Saying nothing, the man tries to walk away, but the teen grabs his bags of food, ripping them out of his hands as the delivery man pleads with him.

The bags tear and the soy sauce and food spills out onto the stairs. As the teen continues to taunt him, the delivery man decides to fight back, striking the boy several times in the head.

The video ends when a man walks out of the building and yells, “Yo, cut that s*** out.”

The commanding officer of the 25th Precinct, Deputy Inspector Thomas Harnisch, confirmed he is aware of the incident but said the police weren’t called and no complaint filed.
