A 19-year-old woman who was allegedly raped and sexually assaulted by two cops while handcuffed in the back of an unmarked van is suing the city, the NYPD and the officers involved in her ordeal.

The teen, who goes by the alias Anna Chambers on social media and Anna Doe in court papers, says in the new Brooklyn Supreme Court filing that now-former NYPD Dets. Eddie Martins and Richard Hall handcuffed, raped and sexually assaulted her in the back of a police van on Sept. 15.

The attack happened in a Coney Island Chipotle parking lot, and then continued as the partners drove through Bay Ridge, according to the court documents, filed Thursday.

Martins and Hall both pleaded “not guilty” to a 50-count indictment in October, and later resigned from the NYPD. Their cases are pending.

In her previously filed $50 million notice of intent to sue, Chambers alleged the men raped and assaulted her in the fast food parking lot.

The suit also alleges Chambers was “intimidated and bullied” by another officer, Greg Markov, and eight other unnamed cops while she sat in an emergency room the night of the alleged rape, “in an attempt to convince her to say the police were not involved in the sexual assault.”

Hall, 33, and Martins, 37, have admitted to having sex with the woman while they were supposed to be overseeing a narcotics bust, but claim the encounter was consensual.

Chambers and her lawyer, Michael David, previously told The Post that a group of nine NYPD officers had shown at Maimonides Medical Center to bully the teen.

“I was sitting in the room by myself . . . They were pressing me, saying things like, ‘Oh, this isn’t the first time you’re having an encounter with the police,’” said Chambers.

A lawyer with the Patrolman’s Benevolent Association declined to comment on Markov’s behalf. Peter Guadagnino, who represents Hall, did not respond to a request for comment.

“This lawsuit, the sworn notice of claim that preceded it and a summary of the complainant’s sworn testimony provided by the District Attorney all provide different accounts of the alleged assault,” Martins’ lawyer, Mark Bederow, told The Post.

“As I have stated previously, Eddie Martins did not sexually assault or forcibly attack the complainant. We expect that will become apparent as the criminal case moves along.”

The NYPD did not immediately respond to a request for comment.

“This lawsuit is to seek justice for Anna Chambers and also send a message to the NYPD that the citizens of this city will not tolerate any sexual misconduct or sexual harassment from its officers,” said David.

“And they have to treat rape victims with respect and not bully them. The fact it took so long to get these cops arrested shows the problem. The NYPD don’t take this seriously enough. This culture of the NYPD has to change. They have to start taking these claims of women more seriously.”

A spokesman for the city Law Department declined to comment, citing the pending litigation.
