He robbed the TD Bank branch at 3735 Walnut Street in University City this morning.
FBI Spokesman J.J. Klaver says he entered the bank about 9 a.m., presented a threatening demand note to a teller and fled on foot with an undisclosed amount of cash.
The robber is described as a black male in his late 20s or early 30s, 6-foot-2, 200 pounds or more, with a mustache and short goatee or facial stubble, wearing a tan bucket hat with an unidentified logo and word on the front, a plain black t-shirt and blue jeans. He was carrying a large black duffel bag and should be considered armed and dangerous.
Anyone with information is asked to call the FBI at (215) 418-4000 or the Philadelphia Police Department. There may be a reward for information leading to his capture, and tipsters can remain anonymous.
