D.C. police are looking for a driver in a car marked with an Uber decal who attacked a woman he picked up.
Police say the female victim told them the male driver demanded sex and refused to let her out of the car.
Police say it happened on the corner of G Street and 11th Street in Northeast near Capitol Hill and the H Street corridor.
It is not clear yet if the driver is one of Uber's partners or just put the Uber decal on his car.
Uber says the woman hailed the car, but did not use their phone app, and their drivers are not allowed to pick up people that way.
D.C. police are not saying where the victim got in the car or how she got away.
Police describe the suspect as a Middle Eastern man around 30 years old. He has a light olive complexion, slim build and short black hair with a widow's peak.
The car had the Uber decal on the rear passenger window. It is a black four-door sedan with grey or beige interior.
"We are working closely with MPD to support their investigation of this disturbing report in every way we can," Uber said in a statement to FOX 5.
Uber says it does federal, state and local background checks on all the drivers who want to partner.
