Which method of detaining a suspect can security guards use?

The method of detaining a suspect that security guards can use is a citizen's arrest, provided it is conducted within legal limits. A citizen's arrest allows an individual—including a security guard—to detain someone they reasonably believe has committed a crime, particularly a felony or a breach of peace. This method must adhere to specific legal guidelines to ensure that the rights of the detained individual are respected, and the detention is justified based on observable actions.

Security guards must be aware of the appropriate circumstances under which they can act, such as witnessing a crime or having reasonable grounds to suspect criminal activity. The ability to execute a citizen's arrest emphasizes the importance of understanding laws related to detainment and the proper procedures to avoid any potential legal repercussions.

The other methods mentioned have limitations that may not align with a security guard's authorized duties. For example, physical restraint might be permissible under certain circumstances, but it can present risks of escalation or legal challenges if not executed correctly. Civil arrest is not typically recognized in the same manner as a citizen's arrest, and preventive detention generally applies to law enforcement rather than private security personnel. Thus, understanding the legal framework surrounding citizen's arrest is crucial for security guards in their role.
