Which of the following responsibilities must a Security Professional perform when making an arrest?

A Security Professional must identify themselves as such and take physical custody of the person when making an arrest. This responsibility is critical as it ensures that the individual being arrested is aware of the authority of the Security Professional and understands the situation. Identifying themselves establishes their position and the legal basis for the arrest, which is crucial for maintaining order and gaining compliance.

Taking physical custody is equally important because it ensures that the individual does not escape and that they are safely and securely detained. This action is often essential for the safety of both the individual and the Security Professional, as well as for the surrounding environment. Properly executing these actions also helps to minimize potential confrontations and misunderstandings during the arrest process.

Other responsibilities, while important in different contexts, are not foundational actions in the context of an arrest as this particular choice outlines. Offering to contact a lawyer may be a considerate gesture, but it is not a requisite part of the arrest process itself. Similarly, merely identifying oneself without taking custody does not fulfill the necessary duties of a Security Professional in this situation.
