Extortion

n. blackmail, use of intimidation or force in order to obtain something (money, information, etc.)

Extortion or outwresting is a criminal offense, which occurs when a person either obtains money, property or services from another through coercion or intimidation or threatens one with physical or reputational harm unless they are paid money or property. Refraining from doing harm is sometimes euphemistically called protection. Extortion is commonly practiced by organized crime groups. The actual obtainment of money or property is not required to commit the offense. Making a threat of violence or a lawsuit which refers to a requirement of a payment of money or property to halt future violence or lawsuit is sufficient to commit the offense. The four simple words "pay up or else" are sufficient to constitute the crime of extortion. An extortionate threat made to another in jest is still extortion.
