Punk busted for pelting NYPD cops with snowballs tried to rob subway rider in ‘prank’ YouTube video

One of the punks arrested for allegedly pelting NYPD cops with snowballs during a raucous melee in Washington Square Park was arrested weeks ago for trying to rob a confused subway rider in what he claimed was a social media prank.

Gusmane Coulibaly, 27, is seen intimidating a stranger and trying to shake him down for cash inside a Bronx subway station on Feb. 6, according to a resurfaced video posted on his YouTube channel — where he goes by the name “Diaperman.”

The stranger bolted towards the emergency exit, where he tried to seek help from a man in a reflector jacket he mistook for MTA police.

“So you gonna pay up?” Coulibaly asked the stranger, the video shows.

“Pay up what?” the other man said.

“My bread, n–ga,” Coulibaly persisted.

“How much you got? Whatever you wanna give, n–-a. F–k me, n–a, I’ve been looking for you for a week straight,” he continued.

“I don’t even know you,” the frazzled man retorted as he picked up his things and tried to flee.

“If I get mad, I’m gonna have to run your pockets, bro. Gangsta,” Coulibaly threatened.

In a last-ditch effort to escape the bizarre situation, the man claimed he was a cop, then approached two men who turned out to be actual police officers.

The officers led Coulibaly over to the far wall and cuffed him, the video showed.

He was arrested and charged with attempted robbery for the subway shakedown — which he claimed was a joke, cops and sources previously told The Post.

On Thursday, he was charged with assault on a police officer, obstruction of governmental administration and disorderly conduct for dunking snowballs on NYPD officers during a snowball free-for-all in Washington Square Park.
