A hateful straphanger rattled off anti-Semitic remarks to a woman in Brooklyn as she threatened to throw her onto the subway tracks, police said this week, amid a disturbing uptick in violence against Jews.

The 41-year-old victim was waiting for a Manhattan-bound 4 train at Utica Avenue in Crown Heights on Dec. 2 at around 6:30 a.m. when the racist stranger began screaming at her, cops said.

“You f–king Jew with the wig … I’m going to throw you on the track,” the fiend declared before following the victim onto the train where the vile rant continued, according to a police source.

The victim endured the angry screed for five stops before getting off the train at Bowling Green.

Her tormentor stayed on the train.

It was not immediately clear what sparked the incident.

The at-large suspect was last seen wearing red sweatpants, a black bubble jacket and a red scarf.

The incident came to light after more than a dozen anti-Semitic attacks over the past two weeks rocked the city.

The NYPD’s Hate Crimes Task Force is investigating the case, which was reported to police on Dec. 2, but not made public by the NYPD until Thursday when the department released a cellphone image of the suspect.

Meanwhile, details of several recent anti-Semitic incidents were revealed by the NYPD on Friday.

On New Year’s Eve, a 36-year-old Jewish woman was walking on Eastern Parkway near Schenectady Avenue in Crown Heights at around 4 p.m. when a man and 17-year-old girl tried to pull off her wig, police said.

The laughing suspects unsuccessfully tugged at the hairpiece before fleeing the scene, according to cops.

Two days earlier a vandal etched swatiskas into the apartment doors of four residents, including two who are Jewish, at an Upper West Side building on West 83rd Street, authorities said.

No arrests have been made in either of the incidents.

Former Assemblyman Dov Hikind, the founder of Americans Against Anti-Semitism, called the wave of anti-Semitism “an epidemic.”

“Things have gotten out of control,” Hikind told The Post Friday as he urged any victims of anti-Semitic hate crimes both past and present to report it to police.

“I urge anyone — even if they called you ‘a dirty Jew’ — to report it,” he said. “We need to know what’s going on … it’s not too late to come out.”
