An unemployed man who went to bed with 90p in his bank account claims he woke up the next morning to discover he was £1.2 million (NZ$2.1m) overdrawn.
Tyler Daniels, 21, said he has been locked out of his account while Barclays conducts a fraud investigation after he noticed the unusual bank statement.
He claims he has now been forced to borrow money from his grandfather and has been left feeling "so stressed" following the ordeal.
Mr Daniels, from Corringham, Essex, said he is unsure why his current account showed that he was overdrawn.
He has now spoken of his horror after claiming he woke up one morning and noticed that his current account showed that he was minus £1,119,999.00.
