A bank heist, also known as a LARCENY or CAPER, is a crime in which a person or group of people steal money or other valuables from a bank. This type of crime is usually planned and executed with the help of an inside source or by using sophisticated methods such as hacking into the bank's computer system. The perpetrators may use weapons or threats of violence to gain access to the bank's assets. Bank heists are often highly organized and involve multiple people working together to carry out the robbery.
