NYC’s largest police union called on the city’s Department of Education chancellor to apologize for teachers and students participating in Black Lives Matter at School “week of action” — which features an NJ cop-killer who remains one of the FBI’s most wanted.

“Disgusting & a slap in the face to families of every PO who died for our city,” the Police Benevolent Association tweeted.

“[Chancellor Richard A. Carranza] should apologize immediately. Glorifying cop-killers unites no one.”

The website for the group that started the week in 2016 quotes Assata Shakur saying: “It is our duty to fight for our freedom. It is our duty to win. We must love each other and support each other. We have nothing to lose but our chains.”

Shakur a former Black Panther who was convicted of killing New Jersey State Trooper escaped from prison in 1979.

The city’s teacher’s union signed onto the national week, which kicks off Black History Month, but it was unclear how many were participating in the event.

The DOE shot back at the PBA saying it “regularly derides black and Hispanic public officials, so it’s no surprise they’re choosing to ignore the facts here and promote divisiveness.”

“Linking a single quote from a national organization’s website directly to lessons in NYC classrooms is baseless, and a weak attempt to degrade and belittle the amazing work our educators do every single day,” a spokesperson said. 

“The Chancellor has nothing to apologize for—he is proud of the work our schools are doing for Black History Month and throughout the year to be culturally responsive and affirm that Black Lives Matter. “
