"The teller complied and the subject fled the scene with an undetermined amount of cash on foot in an unknown direction," police said in a news release.
None of the seven workers and two customers in the bank at the time were injured, police said.
The robber wore a New York Yankees cap, a blue plaid shirt and blue pants. He was in his 30s, about 5 feet 10 inches to 6 feet tall, with a mustache, police said.
