It happened shortly after noon Friday at the Bank of America branch on the 400 block of Market Street.
Authorities say a woman walked into the bank and presented the teller a note demanding money.
The teller read the note and handed it back to the suspect without giving her anything. The woman then fled the scene on foot.
The suspect is described as a heavy-set African-American woman, about 5'4" tall. She was last seen wearing a purple shirt, hooded sweatshirt, and a red scarf on her head.
Anyone with information is urged to contact Camden County Prosecutor's Office Investigator Jeff Dunlap at (856) 365-3125 or Camden Police Sgt. Benito Gonzalez at (856) 757-7420.
