What must a park warden do to arrest someone for an offence?

In the context of making an arrest, it is essential for a park warden to have the individual identify themselves. This step is crucial as it establishes the identity of the person involved in the offence, allowing the warden to collect necessary information for documentation and to determine if further action is warranted. Additionally, proper identification ensures that the individual is clearly associated with the offence being investigated.

While merely observing an offence can provide grounds for action, it is insufficient on its own without further steps being taken. Confirming the seriousness of the offence is also relevant but pertains to the broader context of deciding on the need for arrest or the level of enforcement required. Hence, both of these options do not exclusively meet the requirements needed for making an arrest.

Focusing on the need for identification strengthens the integrity of the enforcement process, ensuring that any further investigation or legal action can proceed based on accurate and verified information.
