Unfortunately the whole banking system is still pathetically useless at actually following where money goes so scammers still get away with their money.
Mad, isn't it? The banks will successfully pick up on and grill you if you have a weekly takeaway habit and are applying for a remortgage that will cost you less than the existing one you've constantly paid on time for years, but something like this can happen - with so many stages of checks somehow passed - and the crooks get clean away with it.
That large amount of money passed through the system electronically, so how can they possibly not know where it went? It's not even like you could launder it across in lots of small, unremarkable amounts, as it's the single lump sum conveyed across as payment for a property.
I can only assume that this bank doesn't actually understand what identity theft is - and as the fraudster has ticked their boxes to 'prove' who he supposedly is, as far as they're concerned, he IS Rev Hall, all sorted, case closed. I'd be very interested to see if they'd wash their hands of the matter so quickly if it had been their CEO who was the victim....
