Internal criminal arrest refers to an arrest method used when a suspect is arrested on suspicion of a crime and the criminal act was committed within his or her place of work or organization. In this case, the suspect is arrested within the organization or company, so it has different characteristics from a general arrest. Internal arrests are sometimes carried out to control crimes and wrongdoing within an organization, and are one of the methods used by police and investigative agencies when conducting investigations into organizations. Internal arrests play an important role in ensuring the credibility and legal compliance of organizations and companies.
