Arrests in legal terms refer to the act of taking a person into custody by law enforcement officials for the purpose of charging them with a crime. An arrest is typically made when there is probable cause to believe that the individual has committed a criminal offense. During an arrest, the person's freedom of movement is restricted, and they are usually taken to a police station or jail for booking and processing. The individual may be held in custody until they can appear before a judge for a bail hearing or arraignment.
