A bank robber held up a South Broad Street bank branch Monday morning, making off with an undisclosed amount of cash, and is suspected by police to be responsible for another bank robbery last week.

The unknown thief handed a note to a teller demanding cash at about 9:40 a.m., police said. He then fled the PNC Bank branch at 230 S. Broad St. and headed in an unknown direction.

He is described as a black man in his 30s, about 5 feet 10 inches, with a medium build and complexion and wearing eyeglasses. He wore a black winter "puffer" vest with a long-sleeved black shirt, blue jeans and a black wool cap.

Investigators believe he is also responsible for the attempted robbery of a Beneficial Bank branch at 16th and Chestnut streets.
