An NYPD lieutenant alleged in harrowing detail how the department’s hulking top cop exploited her financial and emotional vulnerabilities to repeatedly sexually humiliate her in his office at police headquarters, according to a new complaint.

Lt. Quathisha Epps was facing foreclosure and desperate to keep her home when department head Jeffrey Maddrey first asked for sex, she claimed in an exclusive interview.

“He wanted to have anal sex, vaginal sex, oral sex,” the mother of three said.

“He always asked me to kiss his penis.”

Maddrey strongly denies Epps’ claims.

In one painful session, he bent her over a sofa in his 13th-floor office, she claimed to the Post while sobbing.

“I kept asking him, ‘Can you please stop?’ Then I stopped asking him to stop.

“‘Can you please just slow down? You’re hurting me! You’re hurting me!’ “, she claimed.

Epps, 51, recently made headlines for being the NYPD’s top earner, earning $400,000, including more than $200,000 in overtime.

The chief, the force’s highest-ranking uniformed police officer, demanded “unwanted sexual favors in exchange for overtime opportunities” between June 2023 and Dec. 16, 2024, according to an equal employment opportunity discrimination lawsuit filed against the city on Saturday.

She claimed Maddrey also used what he knew about her past as an incest survivor to take advantage of her, the complaint says.

“I think he’s a predator,” Epps said.

“He’d say, ‘We’re going to save your house,’ like you’re supporting me when all you really want to do is fuck me.”

When he wasn’t demanding sex, he forced Epps to perform strange favors for other female officers, according to the lawsuit filed by her attorney, Eric Sanders.

The EEOC document is a precursor to a lawsuit.

Maddrey ordered Epps to keep two mistresses separated because “he didn’t want them to find out about each other,” Epps claimed.

Epps worked as an administrative officer for Maddrey as he rose in the NYPD from housing chief to patrol chief, but his alleged sexual demands did not begin until June 2023, when he became department chief and was responsible for the entire 36,000-strong force, Epps alleged in the complaint.

She then claims she confided in him that she was facing bankruptcy and foreclosure.

“He told me I could work all the overtime I needed,” she remembers.

“He told me I was like his sister.”

But Epps said the favors he requested were anything but familial.

He frequently sent her messages saying “DAP” – slang for “Dat ain’t py” – meaning he wanted anal sex, Epps claimed.

He would also come into her office and “ask me to kiss it,” she alleged in her complaint, a reference to his penis.

He constantly told her he had “a wish and an order” and that she had to do what he said, she claims.

“He would say, ‘Take off your clothes for me now,'” Epps claimed.

Bizarrely, he ordered her to pay for Maddrey and his wife Helen to vacation in Miami, Epps alleged in her complaint.

“There was one trip that I paid for $2,700,” she recalls.

“He said he wanted it to look like a gift. He has a whole script of what to say (to his wife).”

He also allegedly asked her to give her family’s Lower East Side apartment, which was in her children’s names, to a detective who worked for Maddrey.

The first alleged sexual advance with Epps occurred in June 2023, when Maddrey sat at his desk with his uniform pants open and rubbed his chest through his white undershirt, Epps alleged.

“He said he dreamed about fucking me in my ass,” Epps claimed.

“I said, ‘But boss, you’re the department head.’ . . . He was like, “But I’m still a-r and you look good.”

He then asked her to go to the back room of his office, where he had a couch and a bathroom, she said.

“He bent me over the arm of the sofa and when I tried to back away he said to me, ‘Let me just tuck in a little,'” she claimed.

Next, he reached into a locker near the couch, grabbed a jar of KY jelly from a top shelf in the back and rubbed it on himself, she alleged.

When she asked him to slow down, he said in a gentle voice, “I’m not trying to hurt you, baby. “I’m not trying to hurt you,” she recalled.

Epps claimed the two had sexual intercourse about 10 times after that.

Epps, who claims she was raped by a relative since she was four, said she was afraid to tell anyone about Maddrey.

“Who should I tell?” she said.

“Who would believe me?”

The last alleged sexual encounter occurred Monday after Epps went to Maddrey and said she wanted to retire after the Post exposed her excessive overtime, the complaint says.

Maddrey told her he would speak to Police Commissioner Jessica Tisch on her behalf – but first asked her to “kiss” him, meaning his penis, the EEOC document says.

Epps, feeling she had no choice, “complied under duress,” the complaint says.

Immediately thereafter, she filed for retirement, “marking the culmination of the severe emotional and professional harm inflicted on her by Chief Maddrey’s abuse of power.”

The department then suspended Epps and opened an investigation into her.

Maddrey disputes Epps’ claims.

“What an opportune time to accuse someone of misconduct after being caught stealing time,” said Maddrey’s lawyer Lambros Lambrou.

“She is clearly drowning and at the deep end of the pool without a lifesaver. She wants to take out as many people as possible. This is completely unfounded and we deny every aspect of it.”
