Police arrested two men last week accused of putting credit card skimmers in several locations.
An employee found one at Community Supermarket in Lower Burrell.
Surveillance video shows the men placing a skimming device on a card reader.
More skimmers were found at the Community Supermarket in Penn Hills and Shop 'n Save in Scott Township.
Police arrested Thomas Fuchs and David Lechner on conspiracy charges.
Lechner is from Romania, and that's not his real name.
