This happened last month.
Admittedly an impressive one, but thefts are not rare in EVE.
@Richard - the bank is 100% player run and owned. There is no official bank service in the game. Money most definitely is finite, even though they have a lot of it.
@Anon "Laissez-faire or double standards" - buying ISK via time codes is a lot more expensive than via 3rd parties. It is also well controlled so there is no chance of scamming while all the chinese gold farmers will just take your money and never send you the cash, or infect you with a keylogger then clear your cash out.
@Feef - scamming, metagaming, etc is all within the rules, he only got b& for selling ISK for IRL money, which is not allowed.
