The NYPD is conducting an internal investigation after a former cop claimed her superiors did nothing to address her complaints that she was allegedly raped and beaten by her co-workers in a Harlem precinct over a period of years.

Maria Mendez claimed she was repeatedly raped and forced to perform various sex acts on her partner, a fellow police officer from the 32nd Precinct in Harlem, and other colleagues, as well as an FDNY EMT, according to a 54-page notice of claim filed Monday with city Comptroller Scott Stringer’s office.

Mendez alleged that starting in June 2014, her partner and several others “plied her with alcohol, stolen opioids (Oxycodone, Percocet) and MDMA aka Molly which they sold to her, then under physical and psychological threat, force her to perform deviant sexual acts,” the notice states.

She claimed similar abuse started years earlier, in 2006, when “she endured endless sexually offensive comments, physical and sexual assaults from colleagues and supervisors,” the document further states.

She reported the alleged abuse to supervisors, who are named in the court document, as early as 2006, and finally on Jan. 28, 2019.

Mendez, along with her attorney, Eric Sanders, intends to file a $90 million suit.

She resigned from the police department in January, with 14 years on the job.

In a statement to The Post, the NYPD said it will review the claim and “initiate any appropriate action.”

“The NYPD urges anyone who has been a victim of sexual assault to file a police report so we can perform a comprehensive investigation, and offer support and services to survivors.”
