A person who engages in banditry is known as a bandit and primarily commits crimes such as extortion, robbery, kidnapping, and murder, either as an individual or in groups.
Banditry is a vague concept of criminality and in modern usage can be synonymous with gangsterism, brigandage, marauding, terrorism, piracy, and thievery.
