Bank robberies, also known as HEISTS, are criminal acts in which a perpetrator steals money from a bank. They can involve the use of force, threats, or other forms of coercion to gain access to the bank's assets. Bank robbers may also use explosives or other weapons to gain access to the bank's vault or safe. In some cases, bank robbers may even take hostages in order to ensure their escape. Bank robberies can be extremely dangerous and often result in serious injury or death.
