To be honest I didn't hear about this case but I am not surprised. Banks and bankers have often been involved in many scandals like other users before me pointed out, and wherever there is a lot of money there is always a possibility of fraud. Another reason why the blockchain is such a revolution. Imagine if in 10-20 years banks were using a blockchain. A public, verifiable ledger and we could all see the movement of their money. I would be interested to see who has the guts to send/invest it somewhere where it is not supposed to go?!
