Warning: Graphic language

NYPD investigators are looking into whether a black probationary cop crossed the line in 2016 when she made a racially-charged rap video — declaring “war against the white man on the beat.”

The officer has tried her best to scrub the footage from social media, but at least one clip still remains on Instagram.

“It’s the war against the white man on the beat — with his handguns, quick to pull out on a n–ga if he dare run,” says Atisha “Nukstarr” Samuel, now a probationary cop serving the Midtown North Precinct, according to police sources.

“They say we gotta make America great again, we were never great, we were slaves and caged in,” the 26-year-old adds, as images related to police violence flash across the screen.

“They see us like a gorilla in a jungle…So we gotta get it…A black ski mask and a black fitted…Got my crew and a couple hittas…My momma need bread so Imma go and get it.”

Needless to say, Samuel’s brothers in blue are a bit worried about where her loyalty lies.

“I don’t feel safe,” said one cop. “How can I trust she will have my back?”

Another officer added, “If a white cop said that about blacks he would be fired.”

Samuel, a native of Queens, still maintains a relatively quiet public profile as a lyricist since joining the force in October 2016 — just one month before the controversial video was posted. She pops up on rap websites ever so often, including the popular mixtape distributor DatPiff.

According to the site, she was last online Wednesday.

“Born in South Jamaica Queens, New York, Atisha ‘Nukstar’ Samuel was surrounded by poverty and drugs which formed her passion in writing,” her profile says. “In her early childhood days Nukstarr showed a huge interest in arts & music…At the age 13 Nukstarr and her family relocated to Elmont Long Island New York, which she then joined a rap team named Kreamo…By 2009 Nukstarr graduated high school and focused on trying to enroll in college. She put music aside for the next 2yrs. Until enrolling into Cuny York College in Jamaica Queens releasing a mix tape called A New York Girl.”

Samuel has released a number of songs and videos online, which have racked up hundreds of views and listens.

The video being probed by the NYPD was released to help promote her mixtape “Dreams for $1.00.”

Sources said investigators from Manhattan South Inspection were looking into whether Samuel did anything to violate the patrol guide.

In the footage, the officer can be seen alongside her fiancée wearing a black ski mask and t-shirt, which gives the definition for “Negus” — a term used to describe royalty in Ethiopia.

Images related to police shootings and violence in recent years periodically flash across the screen, including photos connected to the killings of Sean Bell and Eric Garner.

The Post reached out to the NYPD for comment about the video, but they had yet to get back with a response as of 10 p.m. Thursday.

Cops said Samuel is still on active duty in Midtown North.
