A Long Island school district has come under fire after teachers at a mostly minority middle school displayed a photo collage that included images of two nooses marked “back to school necklaces,” according to reports.

The offensive photo, which was displayed inside a classroom at Roosevelt Middle School, also included the words “ha” and “#yes,” according to NBC News.

Arthur Mackey Jr., a pastor at Mount Sinai Baptist Church in Roosevelt, said a teacher at the school shared the sickening photo with him.

“Once that was brought to my attention and I saw the picture, we knew that we had to stand up and inform the public,” Mackey told NBC News on Sunday. “All we’re asking is after a thorough investigation, that whoever is involved in this racist image be fired.”

The pastor, who posted the photo on Facebook, said he confirmed its authenticity with other teachers before contacting administrators this weekend.

The district said in a statement that it was made aware Thursday of the “inappropriate conduct” of an “isolated group of teachers.”

“An investigation was immediately initiated, and appropriate action taken,” the district said, adding that it has “zero tolerance for the display of racially offensive images.”

It said it was unable to comment further “as this is a personnel matter.”

As of the 2017-18 school year, the school’s student body is 55 percent Hispanic or Latino and about 45 percent black or African-American, according to the state Education Department.

Mackey said the Roosevelt school district was under state control from 2002 to 2013 and was removed from the state’s list of “struggling” schools in 2016.

“We’ve come such a long way with their grades,” Mackey told NBC News. “For a teacher to do this is a humiliating situation.”

Hempstead Town Supervisor Laura Gillen called for those responsible to be fired immediately.

“This imagery that was on display in a Roosevelt Middle School classroom is undoubtedly racist and should not be tolerated in our town, or any other community,” Gillen told WNBC.

“The imagery is also deeply insensitive and troubling to anyone with mental health issues and those contemplating suicide,” she added.

Community member Savitri Lekhram told News12 Long Island that “it’s probably a joke, it probably has nothing to do with African-Americans,” adding: “But at the same time, they could still draw that connection.”

Another resident, Yvette Hudson, said: “I’m just glad my kids are out of there right now. I was very upset about it.”
