I don't know if this was answered but the Secret Service investigates Bank Fraud. Like Q said, logical. Apologies if it has. Didn't see it in the notables.

Bank Fraud Investigator

Although many financial institutions employ their own bank fraud investigators, and local law enforcement is often involved in investigating such crimes, it is the U.S. Secret Service that is responsible for maintaining stability and integrity of the country’s financial framework and payment systems. In its role as bank fraud investigator, the Secret Service investigates such crimes as:

Counterfeiting

Identity Theft

Check Fraud

Automated Payment Systems Fraud

Direct Deposit Fraud

Check Forgery and Alterations
