The thefts seem to have started a few weeks ago. People who used the drive-up ATM at the PNC Bank location on Georges Road were having hundreds of dollars swiped from their accounts, even though they had their cards with them.
Police say a skimming device was loaded onto the ATM after hours.
It shuts the machine down for a few minutes and loads its information so when customers insert their cards, their banking information is stolen and the thief can download them onto fake cards.
Bank security cameras caught images of a suspect that police are now trying to identify. It is believed he has withdrawn money from ATMs in several counties.
As customers check their statements, they have been returning to the branch and having their money reimbursed by the bank -- and receiving new cards.

Police suggest upgrading to cards that you can just tap without inserting -- and be extra vigilant.
PNC Bank customers who notice suspicious activity linked to ATM withdrawals should notify police and PNC Bank.
