OK. Look at this:
Nigerian Check Cashing Scam The Nigerian check cashing scam usually involves transferring funds internationally. The scam artist attempts to reassure the victim by offering apparently legal contracts, forged or false documents bearing company letterhead, false letters of credit, payment schedules and bank drafts.
Once the scammer has obtained the victim's trust, checks, money orders or wire deposits are sent to the victim for "processing." The victim is asked to cash the check or money order (wire deposits will send the money directly to the victim's account) and send a percentage of the funds back to its origination. The need for the "middle man" is often explained as being a way around international fees or taxes. Once the funds are sent back to the scammers (usually the victim is told to keep a percentage for themselves, as payment for their services), the victim's bank or financial institution learns that the check/money order/wire transfer was fraudulent. The funds are then subtracted from the victim's account and he or she is made liable for the lost money.
