Which type of service involves the execution of a legal order to arrest or detain a person?

The type of service that involves the execution of a legal order to arrest or detain a person is warrant service. Warrant service specifically refers to the enforcement of an arrest warrant issued by a court, which authorizes law enforcement to apprehend an individual. This legal process is a critical aspect of law enforcement operations because it upholds the rule of law by ensuring that individuals who are suspected of committing crimes are legally detained and brought before the judicial system.

In this context, warrant service encompasses the procedures and protocols that officers must follow when apprehending a suspect, ensuring that their rights are respected and that the arrest is conducted safely and appropriately. It highlights the importance of legal authority and accountability in law enforcement actions.

Other options, while related to legal processes, do not directly refer to the specific act of executing an arrest or detention order. Civil procedure involves the rules and processes governing civil lawsuits, court order service refers to the delivery of legal documents or orders, and custodial action relates more broadly to the confinement of individuals but does not inherently imply the specific legal authority provided by a warrant. This distinction clarifies why warrant service is the correct response in this scenario.
