The man entered the bank at 115 East 1300 South, on Wednesday, and handed a note to the teller demanding cash. The teller complied and the suspect fled the bank.
A witness saw a red Kia leaving the area but it is unclear if it was involved.
The suspect is described as an adult white male about 30 to 35 years old. He is about 5 feet 6 inches tall, 150 pounds, with a moustache, bad teeth and bad complexion. He was wearing a black hooded sweatshirt, blue jeans and running shoes.
No weapon was seen and no one was injured.
