Kidnapping is the unlawful act of taking someone against their will, usually for the purpose of extracting money or other goods in return for the release of the victim. It is considered a serious crime in most countries, punishable by extensive prison sentences. There are two main types of kidnapping: abduction and false imprisonment. Abduction is the forcible taking away of a person by another. This type of kidnapping can involve the use of threats, fraud, or coercion. It is sometimes referred to as a "snatch and grab" kidnapping. Abduction is the most common type of kidnapping and often involves ransom demands. False imprisonment is the confinement of a person without legal authority. This type of kidnapping may involve the use of physical restraints, such as handcuffs or ropes, or psychological restraints, such as threats or intimidation. False imprisonment is often used as a form of extortion or coercion. In some cases, kidnapping may also be considered a form of human trafficking, which involves the transportation of people against their will for the purpose of exploitation.
