LOS ANGELES (AP) — Los Angeles authorities are warning the public about an emerging trend of so-called shoulder surfing crimes targeting people using ATMs.

Officials say thieves loiter near an ATM and watch a customer enter their PIN number. When the customer leaves, the thieves quickly approach the ATM, re-enter the PIN before the system logs out, and then withdraw cash.
