What physical action may need to be taken after telling a person they are under arrest?

When an officer informs an individual that they are under arrest, gaining physical control of the person is a critical action that may need to be taken. This is important as it ensures the safety of both the officer and the individual being arrested. If an officer has declared a person under arrest, it is their responsibility to secure the person and prevent any potential escalation or attempt to flee. This step is crucial because, once the arrest has been communicated, the individual may react unpredictably, either by resisting the arrest or attempting to escape.

In situations where physical control is not established promptly, there is a higher risk of the scenario turning volatile, which could lead to injuries or complications in the arrest process. By securing the individual effectively, the officer can then proceed to perform further necessary actions, such as conducting a search, reading rights, or calling for assistance if deemed necessary. Gaining physical control ensures that the entire arrest is conducted safely and within the bounds of the law.
