Extortion (also called shakedown, outwrestling, and exaction) is a criminal offense of obtaining money, property, or services from a person, entity, or institution, through coercion. It is sometimes euphemistically referred to as a "protection racket" since the racketeers often phrase their demands as payment for "protection" from (real or hypothetical) threats from unspecified other parties. Extortion is commonly practiced by organized crime groups.
