Qwai Tilgham, 29, has been charged with both crimes.
Police say that on Sept. 3 Tilgham robbed an 82-year-old woman exiting Taffy's Food Market. They say that on Monday he robbed the TD bank in the 300 block of Delaware Avenue.
Police say Monday's robbery happened around 8 a.m. when Tilgham entered the bank and displayed a note demanding cash. He then fled.
Police say that as Tilgham was awaiting arraignment for the first robbery a detective noticed similarities between him and the bank robbery suspect. Tilgham later acknowledged committing both robberies, according to police.
