Leslie McFadden, one of the letter’s signers, told The Post she expected a swift and thorough investigation when she reported her rape to the NYPD in October 2015 but instead, she was tricked into closing the case.

Leslie McFadden, one of the signers, said Thursday she was “ecstatic” that the Justice Department had decided to act. Police officials have acknowledged investigators made grave errors in the investigation into her report that a former colleague drugged and raped her in October 2015.

Leslie McFadden used to be a New Yorker. Now she calls California home.

A move across the country because of one night in 2015.

“I was drugged and raped in 2015,” McFadden told NY1. “And I did try to stick it out for a few years, but the trauma was just too strong.”

Leslie McFadden, a Lake City native, walks on the catwalk last week during the fourth annual Survivor Fashion Show in New York City. McFadden was drugged and raped in 2015.

“It's time the NYPD be made to care,” Leslie McFadden said. “We need top down changes in how the NYPD investigates sexual assault cases. We need better trained detectives who will treat traumatized victims with compassion and conduct thorough investigations every single time. It's not too much to ask.”

“Even if you have one victim, that’s one victim who may never get justice because they have been failed by the NYPD,” Leslie McFadden told The Post.

Seventy percent of women who say they have been raped don’t pursue charges, a police source said. Those who do, endure an invasive physical exam that can often be retraumatizing, McFadden said.

Leslie McFadden testified she was drugged and raped by a co-worker six years ago.

“My experience with the NYPD, however, was far worse,” she said. “The very first question [the detective] asked me at the start of the interview was whether this was really a case of sexual assault — or just a case of regret.”

Leslie McFadden, 40, who the police believe was drugged and raped by a co-worker in 2015 in Brooklyn, said she hoped the investigation would continue. Days after she was attacked, a Special Victims detective who Ms. McFadden said was brusque and dubious of her claims pressured her to call her attacker on a recorded line.

McFadden, who alleges she was tricked by an SVD detective into closing a complaint against her attacker, said last year that, “From the very beginning, I was lied to, I was dismissed. … It has been a gut punch to deal with [the NYPD].”
