Andrew Laviguer walked into a Wells Fargo bank in Portland, Oregon, pulled out a gun, and robbed the bank of an unspecified amount of money.
After escaping to his getaway car, Laviguer discovered he had a problem: he left the car keys inside the bank.
Police were already on the way, so instead of going back inside to retrieve them, Laviguer hid in a nearby office building.
He was eventually found and arrested by police, who said Laviguer is the main suspect in five other robberies.
The gun Laviguer used in the robbery was fake.
