A transgender woman was raped inside a bathroom at the historic gay bar Stonewall Inn this weekend, according to police.

The incident happened around 11:40 p.m. Saturday night when the 25-year-old victim was inside a single-occupancy unisex bathroom at the bar on Christopher Street. She told police that a man came into the bathroom claiming he only needed to wash his hands, then proceeded to grope and rape her.

The man fled the scene, and the victim also left the bar after the incident. She returned about an hour later, and called 911. She was taken to Lenox Hill Hospital for treatment.

Cops say no arrests have been made, but they're looking for a man in his 30s.

The Stonewall Inn gained permanent landmark status last year.
