Document issues - Urgent advice needed

Hi all,

I've recently authorized a business partner to withdraw some lecit funds earned by me through an online affiliate program to his personal offshore bank account.
We're talking of an amount in the 5digit range.

The company made no objections about wiring funds to him but his bank has obviously asked for some papers proving the origin of such funds so I've asked the company to issue a document where they stated how I've earned such money.
This document has been printed on their letterhead and was obviously showing my full address and personal details so I've authorized my partner to edit the pdf file at his own risk with his own data and he did that successfully through a pdf editor.
He sent it by email to the bank and for some reasons resent a second time another email with some additional info about this transaction by attaching again the file.
But ... This second time he has accidentally attached the ORIGINAL FILE still left on his desktop !

Now it's obvious for the bank that he tried to cheat I guess considering they got the same document with an identical signature and two diff. statements on it.
It was his first deposit to the bank and this incident happened now during the weekend so we can't yet know what will happen tomorrow.

Funds haven't been yet credited to his account but kept on hold by the bank while waiting for this document.
Now he'll obviously lose his account but what should we do to avoid any possible legal isues ?
We can just hope the bank will resend our money back to the source company.

What should he do once the bank will call him for an explanation ?
Any advice to solve this mess in the best possible way ?
Ok, no chance to save his account but the important is getting funds back and avoiding any possible legal issues.

The account was in Georgia and payment has been rejected with the following motivation: According to the bank internal policy, the payment has been refunded.
The account hasn't been closed yet and he has no advantage in making any further questions at the moment.

No legal consequences it seems and this's for sure the best part of this negative experience and his stupidity.

Honestly we can't know if they'll still give him a chance to continue using his account.
