What does "Arrest" refer to in legal terminology?

In legal terminology, "Arrest" specifically refers to the act of legally detaining a person who is suspected of committing a crime. This process involves law enforcement taking an individual into custody, generally following the establishment of probable cause that the individual has engaged in unlawful activities. The purpose of an arrest is to ensure that the individual can be charged with a crime and brought before a court for due process.

This definition is distinct from the other options. For instance, releasing someone from custody means they are no longer under arrest, and issuing a search warrant pertains to seeking permission to search a location rather than detaining an individual. Bringing someone to trial refers to a later phase in the legal process after an arrest has taken place and charges have been filed. Thus, the correct understanding of the term "arrest" is centered on the actual detainment of a person in connection with criminal activity.
