Police have released the latest picture of a woman suspected of robbing four Fairfax County banks since Feb. 26, including most recently a bank in Vienna.

In each case the woman passes a note to a teller that implies she has a weapon and demands cash. Authorities say she flees the area on foot and in at least one case, was spotted jogging as she made off with an undisclosed amount of cash. In none of the robberies has the woman displayed a weapon.
