The law-enforcement officer shall have power to make an arrest for a violation of any law or ordinance relating to the operation and use of the property. The district court in the city or town where the offense occurs shall have jurisdiction of all cases arising therein, and the district court of the county where the offense occurs shall have jurisdiction of all cases arising therein. It shall be the duty of the attorney for the Commonwealth for the locality wherein the offense occurs to prosecute all violators of the ordinances of the locality that pertain to the operation and use of the property enumerated in this section.
