Bank Robbery is a type of theft in which an individual or group of individuals use force, threat, or intimidation to unlawfully take money or assets from a financial institution. It is a federal crime in the United States and can involve the use of firearms and explosives. There are three main types of bank robberies: armed robbery, unarmed robbery, and bank burglary. In an armed robbery, the perpetrators enter a bank with weapons and demand money from the tellers. They may also threaten the safety of customers and employees. Unarmed robbery involves the perpetrator entering a bank without weapons or disguises and demanding money from the tellers. Bank burglary involves breaking into a bank after it has closed for the day, usually with the intent to steal cash or valuables. This type of robbery involves the use of tools to gain access to the building.
