A rumour on WhatsApp that Metro Bank — one of the most common sights on the British high street — has led to a run on the bank, with hundreds of customers queuing up to withdraw their money.
The messages began circulating in west London community WhatsApp groups on Saturday, 11 May, and people started queuing up to withdraw funds from the bank, which was the first to introduce seven day opening to Britain.
Metro Bank spokesman Abigail Whittaker said it was very localised.
"We're aware there were increased queries in some stores about safe deposit boxes following false rumours about Metro Bank on social media & messaging apps. There is no truth to these rumours and we want to reassure our customers that there is no reason to be concerned," Ms Whittaker told the Evening Standard newspaper.
The messages on WhatsApp suggested customers go down to their Metro Bank branch and withdraw their belongings from safety deposit boxes, because the bank was supposedly trying to take ownership.
The Sri Lankan Tamil community in north and west London, which apparently deposits large amounts of family gold at the bank, was particularly spooked.
The bank's shares have plummeted by 75 percent since January after it unveiled plans to raise money to plug a funding gap left by an accounting error.
On Sunday, 12 May, Metro Bank said its plans to raise an extra £350 million to strengthen its finances were "well advanced".
The bank's chief executive, Craig Donaldson, told the Financial Times it was considering selling on more than £1 billion of loans which had been affected by the accounting error.
The last major run on a UK bank was in 2007 when customers of Northern Rock began queuing up to withdraw their money after dire reports emerged of the building society's financial situation. Eventually, the UK government stepped in and effectively nationalised it.
