Which of the following is NOT an alternative to arrest?

Immediate detention is considered a method of restraint rather than an alternative to arrest. In the context of law enforcement, alternatives to arrest typically involve options that allow officers to address a situation without taking a person into custody. This can include actions such as issuing a warning or a penalty notice, or even deciding not to take any action at all based on the circumstances.

Options like no action, warning, and penalty notice serve as options for officers to resolve minor incidents or offenses without resorting to the more severe measure of arrest. Immediate detention, however, implies that the individual is being confined or restrained, aligning more closely with the nature of an arrest rather than providing an alternative to it. Thus, it does not fit within the framework of alternatives that law enforcement would typically consider.
