Police are looking for a man in a black Adidas track suit and sunglasses who robbed a Wilsonville bank by catching an Uber to the scene and then using the same car to flee - unbeknownst to the driver.

The robber, dubbed the "Ride-Share Bandit" by the Clackamas County Sheriff's Office, used a note to demand cash from a cashier at an Umpqua Bank branch on Southwest Gwen Drive in Wilsonville, said spokesman Sgt. Dan Kraus. The driver dropped him off near a Fred Meyer in Northwest Portland after the robbery.

The Sheriff's Office described the robber as a man in his 30s or 40s, about 6-feet tall with a thin build.

The suspect flagged down the driver - whose car displayed both Uber and Lyft stickers -- in downtown Portland, Kraus said. The soon-to-be robber claimed he didn't have an account with either service, but said he would pay cash for a ride.

The driver took him to the bank, waited in the car outside as the man went in, Kraus said, and drove them both away after the robbery. Surveillance video from outside the bank showed the car and its license plates, which allowed investigators to track down the driver.

The driver was interviewed and didn't know what his passenger had done, Kraus said. Authorities don't plan to charge the driver, he said.

Investigators ask anyone with information on the robbery to contact the Sheriff's Office tip line at 503-723-4949 or complete an online form and reference case number 17-25691.
