UPPER DARBY, Pa. (CBS) — Police in Upper Darby now believe they know who they’re looking for in connection with a recent string of bank robberies.

Jermaine Coleman, 31, of West Philadelphia, is now being sought for three holdups at banks in Lansdowne, Upper Darby, and Yeadon (see previous story).

Upper Darby police superintendent Michael Chitwood says earlier photos of Coleman’s holdups caught the eye of another bank teller, who recognized him from a recent business transaction.

“He applied at a fourth bank for some type of loan, and as a result of that they called us,” Chitwood told KYW Newsradio today.

Coleman was believed to be driving a late model Dodge Charger with Florida plates, perhaps a rental.

In all three incidents he produced a note threatening to use either a gun or a bomb, so he’s considered armed and dangerous.

Police estimate he’s gotten away with more than $6,500 in the three holdups.  Anyone with information on the whereabouts of Coleman is asked to contact Upper Darby police.
