Police in Berks County could have a serial bank robber on their hands.

Police were dispatched to the Susquehanna Bank on the North Fifth Street Highway in Muhlenberg Township just before 4 p.m. Tuesday.

The robber handed a teller a note demanding money, but police said he thought the teller was taking too long and ran off. He was last seen on foot in the Cherokee Ranch development.

Police said they believe the same man robbed the Metro Bank in Exeter Township on July 25.

Exeter investigators have said they believe he is also behind a robbery in Baltimore County, Maryland.
