ROCKVILLE, Md. (AP) - Montgomery County Police say credit card skimming devices were placed on ATMs at banks in the Bethesda and Chevy Chase areas.
Police say the devices, which recorded account numbers, were put on ATMs several times in August.
Officers say the account numbers were later used fraudulently.
Detectives urge consumers to inspect credit card readers at ATMs, gas pumps and elsewhere before using them. People should check for parts that are loose, crooked or damaged, or for scratches or adhesive or tape residue on the device.
