A terrified woman jumped from a moving Uber car after the driver demanded she pay for her journey by having sex with him, a US court in Chicago has heard.

Muhammad Fahim, 44, faces three counts of unlawful restraint for the incident on 4 July.

He is alleged to have picked up the 19-year-old victim after she requested a ride through the taxi hire app, the Chicago Tribune reported.

Her journey log was somehow deleted from the app, however.

When the woman volunteered to pay with cash, Fahim instead demanded sex from her, Assistant State's Attorney Mikah Soliunas told a court.

When she refused, Fahim is said to have repeatedly locked the car's doors and refused to let her out unless she gave in to his demands.

The woman only escaped when she jumped out of the moving Uber vehicle as Fahim slowed due to traffic, Soliunas said.

She is not believed have suffered injuries.

Fahim was detained after being stopped by Chicago police late Thursday (17 August) for a traffic violation in 500 block of North Dearborn Street.

When officers checked his name, they were alerted to the 4 July incident.

An Uber spokesman described the allegations as "troubling" and said Fahim had been removed as a driver while the company looks into the matter.

Fahim, of the 6100 block of North Washtenaw Avenue, appeared in court but reportedly said nothing during the hearing. He is being held on $100,000 bail.
