Final answer:
A private person making an arrest under the Trespass to Property Act must deliver the arrested person to the police, who will take over the investigation and legal proceedings.
Step-by-step explanation:
Under the Trespass to Property Act, if a private person makes an arrest, they must deliver the arrested person to the police. This is because private citizens do not have the authority to detain individuals for an extended period, and it is the duty of the police to further investigate and process any accusations or charges. It is not permissible for the individual to be delivered to the manager of the store, the teenager's mother, your supervisor, or the paramedics unless there is an immediate medical emergency.
