An FDNY EMT is facing arrest on sex-abuse charges for ​assaulting a patient in an ambulance in Manhattan last year, a police source says.

The Emergency Medical Technician was accused of licking the woman’s breasts and stomach while she was passed out in the back of an ambulance on July 16, 2017, the source said.

The ​accused lech and a coworker were taking the debilitated woman to the hospital. But the​ passed-out woman​ came to while the EMT was ​in the middle of the assault, the source said.

Cops got ​the man’ DNA and were able to secure an indictment for sex abuse in the first degree in Manhattan Criminal Court, the source said.

A warrant has been issued for the man’s arrest.
