The family of the black New Jersey teen who was handcuffed and pinned to the floor by cops who let the white boy he was brawling with sit on a couch has retained civil rights lawyer Benjamin Crump.

The famed attorney — who has repped the families of George Floyd, Michael Brown, Breonna Taylor and Ahmaud Arbery — confirmed Thursday that he has been retained to help 14-year-old Z’Kye Husain.

Crump insisted that the now-viral video of the seventh-grader’s arrest Saturday at Bridgewater Commons mall showed the aftermath of him trying to protect a pal from “being bullied by a much older 11th-grader.”

“It is evident that officers immediately assumed that because of the color of Z’Kye’s skin, him acting nobly was not even in the realm of possibility,” Crump said.

“That video says it all,” he said of the incident being investigated by the police department with the help of the Somerset County Prosecutor’s Office’s Internal Affairs Unit. 

The video caught two Bridgewater cops breaking up the fight — then allowing the older, lighter-skinned boy to sit alone on a couch while they pinned Z’Kye to the floor. One of the officers placed a knee near the back of the black teen’s neck as the two handcuffed him.

“Z’Kye was no more of a threat to those officers than the white teen who fought with him,” Crump insisted.

“This is another example of the kind of racial bias that we need to root out of our system of policing. 

“These officers need to be reprimanded and retrained to overcome the implicit bias that results in unequal — and often dangerous — treatment of Black people,” he said.

Z’Kye — using the shortened first name Kye — previously told NBC News that he never expected it to turn violent when he stood up to the alleged bully.

His mother, Eboné, also said that “it doesn’t take two cops to hold a 14-year-old boy down who’s not resisting, while the other boy is just kind of going free and still going off on my son.”

“It just doesn’t make sense,” she said — also telling ABC News that she wants the cops involved “to become unemployable.”

Gov. Phil Murphy has said he was “deeply disturbed by what appears to be racially disparate treatment in this video.”

The NAACP’s New Jersey president, Richard Smith, called for the officers involved “to be immediately removed from the [police force] pending an investigation.”

“Despite years of talk about bias training and accountability, the video of what happened … cannot be denied,” Smith said.

“The time for the governor and attorney general to put a stop to this type of behavior by the police is NOW.”

A spokesperson for Bridgewater Police Department said Thursday that the force would not comment on the case while it was still being investigated.

Bridgewater Township Mayor Matthew Moench said the investigation was crucial to “absolutely ensure” that use-of-force policies “were upheld in this instance.”

“It is not appropriate for me or any other Township official to comment any further on the details of this incident while an investigation is ongoing,” he said in a statement.

Thanking the public “for its patience in refraining from jumping to conclusions,” the mayor also thanked “the brave men and women” of the police department “for keeping our public safe in today’s challenging environment.”
