Under what authority can a police officer intervene to stop any harm being done in their presence to public property, whether movable or immovable, or to prevent damage or removal of public landmarks, buoys, or navigation markers?

Explanation

A police officer is empowered to act independently to prevent any injury or damage to public property or navigation aids if such harm is attempted in their presence. They do not require prior permission from a Magistrate or Superintendent of Police to do so.
