A bank machine had to be shut down after it started issuing too much money.
The ATM at Clydebank, Glasgow, was said to be giving double the money to customers.
Operator Clydesdale Bank said: "One of our ATMs appears to have issued incorrect cash amounts for a short period.
"We were quickly alerted and it was taken out of service while we investigate."
A spokesman for the bank said the fault was intermittent and the machine was not emptied.
It follows a fault at another Clydesdale Bank ATM in Stewarton Street, Wishaw, North Lanarkshire just days ago.
Customers were able to double their money there on December 4.
