What is the legal term for the act of unlawfully seizing and carrying away a person?

The correct answer is the term "kidnapping," which specifically refers to the unlawful seizing and carrying away of a person against their will. This crime often involves the intent to hold the person for ransom, as a hostage, or simply to commit unlawful acts. Kidnapping is treated as a serious offense due to the violation of a person’s freedom and the potential physical and psychological harm that can result from such an act.

In contrast, robbery involves taking property from a person through force or intimidation, and while it may sometimes overlap with the act of seizing a person, it does not primarily focus on the unlawful confinement of an individual. Attempt kidnapping refers to the intention or effort to kidnap someone without successfully completing the act, which does not apply when the act has indeed been carried out. Murder, on the other hand, concerns the unlawful taking of a person's life and is not relevant to the issue of unlawful detention or carrying away. Each of these definitions highlights why kidnapping is the precise term for the unlawful act described in the question.
