What agency should be notified if a bank is robbed?

The Federal Bureau of Investigation (FBI) is the correct agency to notify in the event of a bank robbery due to its jurisdiction over federal offenses, which include bank robbery. According to federal law, bank robbery is considered a serious crime that often involves a violation of federal statutes since banks are federally insured. The FBI has the resources, expertise, and authority to investigate such crimes thoroughly, often collaborating with local law enforcement agencies as needed.

The local police are also vital in responding to a bank robbery; however, they typically handle initial response and local investigations. The Department of Justice oversees legal proceedings and enforcement of federal law but is not the first line of response. The Secret Service primarily focuses on safeguarding the nation's financial infrastructure and investigating crimes related to counterfeiting and certain types of fraud, rather than directly investigating bank robberies. Thus, notifying the FBI is essential for a comprehensive investigation into the robbery.
