With every government agency comes an investigative arm to ensure its policies are enforced. Given the wide applicability of the mail and wire fraud statutes, almost any federal investigation could result in indictments for mail and wire fraud. Below is a list of federal investigating authorities that commonly bring mail and wire fraud charges:

• Federal Bureau of Investigation
• Securities Exchange Commission
• Bureau of Alcohol, Tobacco, and Firearms
• Drug Enforcement Administration
• IRS Criminal Investigations Division
• Postal Inspection Agency
• Office of Inspector General
• Secret Service

If any of these agencies have contacted you regarding an investigation, it is wise to contact a criminal attorney, whether you are sought as a witness, or if you are being targeted as a criminal wire or mail fraud defendant.
