A Bitcoin ATM started firing out wads of £20 notes in front of stunned commuters at a Tube station in London.

The footage, filmed at Bond Street station near Oxford Street, shows security guards surrounding the cash machine to stop people getting access to the money.

A sheepish customer, believed to be making a large withdrawal, stood near the ATM, with a duffel bag placed on the floor filling up with money.

The customer seemed to be collecting the money in the bag and even used his feet to push the cash closer together.

He is ignored by the security guards as he watches the money pile up.

Several commuters stop to stare at the cash as it pours out of the Bitcoin ATM.

The Polish company that owns the machine said that it started spewing out notes because a customer was withdrawing a large amount of money.

It also insisted that the machine did not randomly start discharging the £20 notes.

Adam Gramowski, owner and CEO of Bitcoin Technologis, claimed his company's machine was struggling to handle UK notes.

He told the Sun: 'As you can see there is a bag in the front of ATM. However our ATMs support large transactions and it is fair to say that a larger, redesigned presenter would be a good solution.

'Our customer was not particularly careful, although the ATM should be redesigned to cope better with small denominations used in the UK.'
