A female University of Michigan student told police that an Uber driver demanded money or a sex act when she tried getting out of the vehicle around 1:30 a.m. Friday.

Uber is a popular ride-sharing service.

U-M police issued a security bulletin about the suspicious incident Friday afternoon.

The student said she joined another person in an Uber ride.

"When the victim attempted to leave the vehicle at her destination, the driver reportedly demanded money or a sex act," the bulletin said. "The victim was able to leave the vehicle and enter her residence without physical contact."

The driver is described as an Indian male, mid-20s, slender build with light brown skin, short black hair and clean shaven.

He was wearing a short-sleeve shirt, possibly a polo style and no glasses. The vehicle was a dark-colored, four-door sedan, possibly a Toyota or Honda.

U-M police offer these risk reduction strategies for using Uber:

Always use the Uber app when securing a ride.

When sharing a ride, all subjects should request their own rides through the app so everyone has the driver's information and Uber has all passenger information.

Anyone with information about the incident, the vehicle or the driver is urged to contact the U-M Police Department at (734) 763-1131 or the university's anonymous tipline at 800-863-1355.
