It happened around 5 p.m. in the 1000 block of Vision Drive.
Officials say no one was hurt and no weapons were used. In fact, police say the suspect moved quickly and quietly.
Police interviewed eyewitnesses and combed through the area for evidence.
Authorities say the woman captured in surveillance photos waited in line behind the last customer, then passed a note to the teller and walked out with an unknown amount of cash.
Police believe the suspect is a white female with dirty brown hair, 5 feet 6 inches tall and weighing about 140 pounds. She was seen leaving the bank in a grey Ford Focus with possible 30 -day tags.
Authorities in Benson say the car description is similar to the car a woman who robbed a bank there on Monday used.
In that case, a woman walked into First Federal Savings and Loan in the 100 block of North Johnson Street around 2:30 p.m. and demanded cash.
At this time, police say they do not know if the two crimes are related. However, the suspect in the Benson robbery matches the same description and also passed a note to the teller, and demanded a specific amount of money. There are too many similarities for investigators to ignore the strong possibility that the crimes are related.
"Female bank robberies are a rarity. The fact that they've had one and we've had one, the suspect vehicle description is the same, obviously makes us wonder if this is something that's tied to ours," said Apex Police Capt. Ann Stephens. "It's really early so we're talking with Benson and we're working with them and comparing notes."
Anyone with information on either crime should call the Apex Police Department at (919) 362-8661, or the Benson Police Department at (919) 894-2091.
