What is the maximum time a security guard can legally detain a suspect?

The maximum time a security guard can legally detain a suspect is usually not longer than a few minutes. This is primarily because the authority of a security guard to detain someone is limited to the time necessary to ascertain the individual's identity or to prevent a crime. Prolonged detention could lead to legal issues, such as accusations of false imprisonment or unlawful detainment, especially if the security guard doesn't have the proper legal authority or justification for holding the individual.

Generally, the acceptable window for detaining someone is brief, and it must be clear that the purpose is to facilitate a quick investigation or to hand the individual over to law enforcement. This duration ensures that the rights of the individual being detained are respected and reduces the risk of legal complications for the security personnel involved.
