where to report suspected international cashiers check fraud?

Answer 1

You can go to most banks and report it. My city just had the fake postal money orders sent to a lady and the bank ran the numbers to find if they were real, and they were not. You can also go to the website below.

So now the scammers have spread to babysitters! As others have stated, there is always a common thread. Fake check to be deposited, a reason why there is too much money, the urgent need to have the excess refunded by you via Western Union, Moneygram or Bank Wire. The other recent variations are the be-a-mystery-shopper check and the I-want-to-rent-your-house deposit. The mystery shopper variant tries to claim you are spending their money to test Western Union's services (actually they are hoping that you won't tell WU what you are doing, because WU is well aware of the scam). The rental variant has the person suddenly claiming their job/trip was cancelled, so they want everything back but the deposit....

It really is simple, you report crime first to your local police department. If other agencies are required either they will contact them or refer you to them.
