If the bank has already informed the authorities and you are on the black list, it is a problem... unless you sort out with the bank and they clear your name . Clearing the name again can be a problem since the offence is a state offence and not a matter of the bank only..

If they have not informed the bank... talking and sorting things out may help.... All depends on the amount... Normally bank may not care about small amounts, unless big enough to cover the cost of following it up...

Big amounts sometimes have had interpol involved as well...

...You can't mean what you say unless you can say what you mean...
