What is the proper term for an arrest made by a guard?

The term "private person arrest" refers to an arrest made by an individual who is not a law enforcement officer, which includes security guards and others in a position to intervene in a crime. This legal concept stems from California Penal Code Section 837, which allows private individuals to arrest someone for a public offense committed in their presence, or if the individual has committed a felony.

In the context of security services, security guards are often tasked with maintaining safety and order within their assigned premises and have the legal authority to detain individuals suspected of committing a crime, provided their actions meet the criteria set forth by the law. This can be particularly important in maintaining safety in environments such as malls, clubs, or corporate offices, where security personnel may be the first to respond to criminal activity.

The other terms presented, while they may seem relevant, do not accurately reflect the legal terminology used for such arrests made by security personnel. Understanding this specific terminology is crucial for those working in the private security field to ensure they operate within the bounds of the law.
