Two correction officers and their supervisor walked the woman from an intake area to an isolated room in an abandoned area of the Rikers Island jail. There, according to a lawsuit, she was stripped of her clothing, handcuffed to a toilet fixture and sexually assaulted for several hours.

The woman said her attackers included a correction captain and two officers, who raped her and penetrated her with a flashlight. They forced her to perform oral sex and rub one officer’s genitals. She was also compelled to drink soapy liquid, she said, and the officers pepper-sprayed her genitals.

The next day, she said, a correction officer took her from the isolated area to a housing unit in the jail and warned: “This never happened. If it is being heard upstairs, things are going to be worse.”

The disturbing account of a brutal sexual assault in 2013 at the Rose M. Singer Center — the jail that houses women on Rikers Island — was detailed in a federal civil rights lawsuit the woman filed against the city initially under seal in 2015.
