PORTLAND, Ore. (KOIN) — Four people were identified by the Washington County Sheriff’s Office as either “suspects or people with knowledge” about the possibility skimming devices were illegally placed on self-service stamp machines at two post offices.
The pictures were obtained by the US Post Office from ATM cameras, Sgt. Bob Ray told KOIN 6 News. No one has been arrested in the case.
Skimming devices are typically chips covertly installed over the machine’s card slot, so that a customer’s card information can be read and stored when using the machine.
Three customers who all used self-service postage machines in Beaverton and Aloha in late March reported large fraudulent withdrawals on their ATM cards.
Access to the machines is not difficult since they are all available after regular business hours inside unlocked lobbies.
The investigation continues through the Washington County Sheriff’s Office and US Post Office investigators.
