While students were out of school for spring break last month, police juvenile officers swept through Maui beaches and parks, making arrests for underage drinking, drug possession and curfew violations, the Maui News reported.

Officers arrested 16 people during "Operation Spring Fling" from March 15 to 19.

Those arrested included 14- and 17-year-old Upcountry boys found with marijuana in Pā'ia on March 15 and 29-year-old Lahaina resident Kamana Ng, who was found with marijuana at Honolua Bay on March 17, police said.

That afternoon, three other men — Lahaina residents Kingston Lindsey, 19, and James Lane, 18; and Jesse Silva, 19, who gave no local address — were arrested at Banyan Tree Park in Lahaina for drinking in a historic district and underage drinking.

Silva also was charged with third-degree promotion of a detrimental drug after a glass pipe containing suspected marijuana residue was found in his backpack, police said. Lane was charged with possessing a prohibited deadly weapon after a throwing knife was found in his pocket, police reported.

All of those arrested were released to parents or released on their own recognizance.

Sgt. David Silva said enforcement targeting criminal activity involving juveniles is ongoing.

"With kids back in school, we'll continue to do our weekend enforcement," he said.
