An Uber driver was robbed at gunpoint in Fontana early Saturday, Aug. 22, while waiting for passengers who were inside a restaurant.

The robbery happened about 3:20 a.m. in the 9800 block of Sierra Avenue after an older-model, dark sedan with tinted windows parked next to the Uber driver. The passenger in the sedan walked up to the driver-side window of the victim’s car and pulled a gun on the 37-year-old Ontario resident.

The female victim handed over an undetermined amount of money.

The gunman was described as a Hispanic male in his 20s with a thin, sunken face, wearing a blue, hooded sweatshirt with a large F on it.

Uber customers use a mobile smartphone application to submit a trip request, which is then routed to Uber drivers who use their own cars. Payment is made electronically.

Uber drivers have been been the victims of robberies and assaults nationwide, both by would-be passengers and others, according to Internet reports. Uber drivers are prohibited from carrying guns. There have been reports of Uber drivers committing robbery, and at least one of someone impersonating an Uber driver and demanding money from his passengers.
