Police said the man, described to be about 40 to 50 years old, slipped the bank teller a note demanding money. The teller complied and the robber stuffed the money into his pocket and walked away.
The suspect wore a blue shirt, dark jacket and tan pants. He also had a mustache, which detectives say may have been fake.
Witnesses said he may have left the bank in a light-colored minivan.
Anyone with information that may help identify the suspect is asked to call the Riverside Police Department at (951) 353-7136.
