A Long Island detective was charged with a hate crime on Wednesday after calling a telephone operator the n-word and spewing “We don’t want you or yours in the neighborhood” in a racist rant, according to officials.

Rockville Center Detective John Murphy, 40, allegedly flew into a hate-filled rage after spotting a black cell service subcontractor inside an SUV on Nov. 3 around 7 p.m. near Sylvan Court and Weeks Avenue in his Manorville neighborhood.

Murphy allegedly lunged at the 48-year-old worker and told him: “Get out of here. We don’t want you or yours in the neighborhood, n—-r,” according to a criminal complaint.

The hateful detective then kicked the victim’s SUV and ripped off a light attached to the top of the vehicle before tearing it into pieces and throwing it at the victim, hitting the left side of his face, court documents allege.

Moments before the violent altercation, Murphy — who was off duty at the time — allegedly asked the victim what he was doing in the neighborhood while identifying himself as law enforcement.

When the worker tried to hand over his ID, Murphy refused to look at him, police said.

Murphy, of Manorville, was slapped with criminal mischief as a hate crime and aggravated harassment.

He ignored reporters’ questions after his court appearance Wednesday.

Suffolk County District Attorney Raymond Tierney criticized Murphy’s allegedly bigoted attack.

“The victim here was just trying to do his job when the defendant allegedly harassed him and damaged his vehicle,” Tierney said in a statement.

“To make matters worse, the defendant is an officer of the law, charged with protecting the rights of citizens, rather than violating them, as alleged here.”

Murphy is due back in court on December 3 and was ordered to stay away from the victim.

The Rockville Center Police Department suspended Murphy Wednesday morning, according to Newsday.
