PHILADELPHIA (CBS) — The Philadelphia Police Department and the FBI are seeking the public’s assistance to identify and locate the person responsible for Sunday’s robbery of a TD Bank in Northwest Philadelphia.

Police say shortly after noon, a man entered the TD Bank along the 5500 block of Ridge Avenue in the city’s Roxborough section and passed the teller a demand note. After obtaining an undisclosed amount of cash, the subject fled the area on foot. He was seen running north on Ridge Avenue, then west on Markle Street.

The subject (seen in photos) is described as a black male in his late 20s to early 30s, approximately 5’9″ to 5’10” tall, medium build, medium to dark complexion, with a goatee and glasses. He wore a black knit cap, black hooded sweatshirt, and black knit gloves.

Police believe the same man is connected to at least four other incidents this month, including the attempted robbery of this same TD branch on Thursday.

Authorities say the suspect is considered armed and dangerous. Anyone with information about this robbery or the man responsible is urged to call the FBI at 215-418-4000 or the Philadelphia Police Department. There may be a reward for information leading to the bank robber’s arrest.
