Close arrest is a term that is often associated with legal jargon used to describe the confinement of a person who is suspected or accused of committing a crime. There are several synonyms for close arrest, including "house arrest," which refers to the confinement of a person within their home or a designated area. Another synonym is "detention," which generally refers to the confinement of a person in a facility such as a jail or prison. "Custody" is also a synonym for close arrest, which implies that the person is under the authority of the state or law enforcement agency. Ultimately, all of these terms imply that a person is confined or restricted in their movement due to legal reasons.
