Letter Source:  This letter arrived directly from Burkina Faso, a small African nation bordering Nigeria.  Scroll down to see the fake letterhead.  Letters like the one below are usually received by victims who refuse to send money, and are an attempt to scare the victim into cooperating.  This is called extortion.  Such letters are often followed by emails from scammers posing as attorneys and demands for payment, and sometimes threatening phone calls.

On the same letterhead, they have listed the FBI, IRS, and Treasury Department, all separate agencies.  There's no such thing as a "Treasury Inspector General for Tax Administration."  We don't have titles like that in the US.  Besides, the Treasury Dept. and the Internal Revenue Service are two separate entities and at least in Washington, are not even housed in the same buildings.

The US Federal Government does not correspond by email for anything like this.  Totally absurd. 

(1) There's no such thing as the "Anti Fraud Department of the US Treasury." 

(2) Anti-fraud is spelled with a hyphen.

(3) The FBI is not an arm of the Treasury Department.  The enforcement arm of the US Treasury is the Secret Service (Department of Homeland Security).

(4) All law enforcement emails end in either @_____.gov or _____@.(state abbreviation), never "@usa.com."  For instance, to report a Nigerian scam mail, you would send it (with the full headers) to 419fcd@usss.treas.gov.  That means 419 (the Nigerian law enforcement code for Nigerian Scam Letters) Financial Crimes Division at the United States Secret Service, Treasury Department, United States Government.

(5) No one is ever notified via email by any US enforcement that a warrant has been issued. 

(6) The Treasury Department could care less if you write to a foreign bank, fraud letter or not.  They don't have the time to chase down any silly letter received by a foreign bank, the foreign bank would have to file a complaint with either the Secret Service or the FBI, and no bank is going to do that if it hasn't suffered a financial loss or is at risk of substantial criminal activity. 

(7) On top of that, one email does not make a fraud.  One email isn't even court evidence except as support to other hard copy evidence.
