FRANKLIN BOROUGH — A teenaged boy was arrested after two girls he supplied with marijuana overdosed on the drug on Tuesday, police said.

Officials are still investigating whether any narcotics were used with the marijuana, police said.

“We’re looking into whether there were any other narcotics were ingested,” said Det. Nevin Mattesich of the Franklin police.

The 17-year-old boy was arrested and charged with use of a controlled dangerous substance and possession of drug paraphernalia, Mattesich said.

The two girls, age 15 and 16, were allegedly given the marijuana by the boy and were found on main street, near the local library, at 5:30 p.m. on Tuesday, Mattesich said.

The girls were both in distress and in need of medical attention, Mattesich said. They were both taken by the Wallkill Valley First-Aid Squad to Newton Medical Center, where they were treated, he said.

An investigation led to the 17-year-old boy, Mattesich said. He was later released to a parent pending an appearance in juvenile court, he added.

Mattesich said borough police officers were going to “aggressively pursue” the investigation – and more arrests may follow.
