NYPD BOO GHOULS

Injured mom sues over H’ween haunt

She says cops don’t know “boo” about safety.

A Bronx mom is suing the NYPD, claiming a precinct’s haunted-house event turned truly ghastly when a cop jumped out to scare her in the dark — but instead knocked her to the ground, breaking her ankle.

Ari Anderson claims she got the scare of a lifetime while visiting the 41st Precinct station house in Longwood with her kids on Halloween last year, according to her lawsuit filed Tuesday in Bronx Civil Court.

While walking through the spooky station house, an officer “lunged” in her direction — startling her and knocking her “to the ground,” she claims in the suit.

“It was pitch back and someone came around the corner,” her attorney, John Clark, told The Post, adding that Anderson fractured her left ankle. “She is still in recovery.” Officers told her she would “soon receive medical attention.”

But she ended up waiting outside the station with no help for “an unreasonable amount of time,” according to the suit.

“Because of the event, they had a lot going on — and they just left her there outside with her kids,” Clark said.

She eventually took a cab home, then to Lincoln Hospital, where a doctor told her she’d need an immediate “open reduction” surgery, the court papers state.

She later had a second surgery to remove hardware implanted during the first operation.

Anderson hasn’t been able to work since the Halloween injury, according to Clark.

“She’s a single mom, so it has been a lot for her,” he said.

She claims the NYPD “failed to act in a safe and reasonable manner” when it hosted the event.

Cops were “negligent in failing to provide adequate lighting for the event and in otherwise operating, managing, hosting and conducting the event,” the suit states.

The NYPD also was “negligent in causing the plaintiff to fall to the ground and sustain the aforesaid injuries,” the suit states.

Cops had a responsibility to “ensure” that the police station was “safe for the public” — but it “breached that duty,” it continues.

The lawsuit also notes officers “did not provide the plaintiff with any medical attention or treatment at the precinct.”

Clark declined to say how much compensation Anderson is seeking over the incident.

In response, the NYPD said: “We will review the lawsuit when we are served.”
