When customers at an ATM machine in Texas heard a faint voice from inside, begging for help, they first thought someone was playing a trick on them.
But this was no joke - especially not for the man trapped inside.
"We come out here, and sure enough we can hear a little voice coming from the machine," Corpus Christi police officer Richard Olden told KZTV. "So we are thinking this is a joke. It's got to be a joke."
A contractor had become trapped inside after he accidentally locked himself into a small room connected to the machine while changing the lock.
He didn't have his keycard or phone on him and was unable to contact any coworkers inside the bank so instead poked handwritten SOS notes to customers through the receipt slot.
Each note had a similar message: "Please help. I'm stuck in here and I don't have my phone. Please call my boss."
Police ended up having to kick down the door to free the contractor, who has not yet been identified. Fortunately, the man wasn't hurt.
