The suspect is identified as Maurice Emile, who escaped from the Wernersville Community Corrections Center in Berks County on Saturday.
Police said Emile, 32, robbed two banks on Monday.
The first holdup happened at the First Trust Bank at 7th and Hamilton streets in downtown Allentown around 11:30 a.m.
Police said Emile then returned to downtown Reading and robbed the Fulton Bank in the 200 block of North 5th Street.
After his escape on Saturday, Emile allegedly robbed the Citizens Bank at North 5th and Penn streets in downtown Reading.
Police say Emile has an account at that bank, and even talked to a customer service representative, giving her all of his information. He then allegedly walked up to a teller and handed over a note saying 'This is a robbery. Give me all your money.'
Police said Emile robbed the same Citizens Bank branch on May 11, 2004. He was later paroled, but picked up again in 2007 for violating that parole with a drug violation.
No one was hurt in any of the holdups.
Anyone with information about the bank robberies is asked to call the Reading Police Department at 610-655-6116 or Crime Alert Berks County at 877-373-9913.
