Dozens of people flocked to a cash machine after word spread that it had started giving out free money.
The Lloyds Bank ATM in Mansfield Woodhouse, Notts, malfunctioned and began spewing out notes as customers withdrew cash yesterday morning.
Around 60 people are reported to have queued up at the hole-in-the-wall as word spread of the possible windfall.
The fault was spotted by bosses and the cash machine was put out of service around 3pm.
A spokesman for Lloyds Bank said investigations had begun into how the error occurred and the group would not be able to provide details on how much cash was taken from the ATM.
It is not yet confirmed if those individuals who cashed in will be pursued to reimburse the bank.
The spokesman said: "We're aware that an error occurred with a Lloyds Bank ATM in Mansfield Woodhouse, resulting in the ATM distributing incorrect amounts of cash.
"The ATM is now out of service and the error is being investigated."
