PLYMOUTH, Maine — A 14-year-old boy was arrested on multiple charges on Sunday after allegedly assaulting and threatening to kill staff members and a resident at a home for troubled youth.

Maine State Police Trooper Jonah O’Roak received a report of two juveniles fighting at the Sweetser School at approximately 10:30 Sunday morning.

“When I arrived there was a 14-year-old being restrained by staff members,” O’Roak said Monday afternoon. “I gathered that the juvenile had assaulted three staff members and another juvenile at the facility.”

The boy allegedly punched and kicked staff members and tried to choke one of them.

The boy, who is not being named by the Bangor Daily News because of his age, allegedly “threatened to kill all four persons with a wooden stake,” he said.

“He picked up a stake and held it over his head and threatened to kill staff with it,” said O’Roak.

The stake was approximately 1 inch in diameter and about 8 to 10 inches long, he said, similar to one that might be used on a lawn.

Staff members were able to get the stake away from him, said O’Roak.

The boy was restrained and staff members and students went to another building, which was locked down during the incident.

“[Staff] let go of him at one point for his own safety. At that point, he tried to break into the other building that was locked down,” he said.

The boy reportedly kicked out a kitchen window in the locked building before staff were able to restrain him until O’Roak arrived.

“He was trying to go after another juvenile when he kicked the window out,” he said. “Earlier, he damaged a door inside the building.”

O’Roak estimated the damage to the school at $400.

The boy, who was on probation, was arrested and charged with four counts of assault, criminal threatening with a dangerous weapon and criminal mischief. He was taken to Mountain View Youth Development Center in Charleston.

The staff members suffered minor injuries and didn’t require medical attention, said O’Roak.

After O’Roak arrived, the boy calmed down, he said.

“He was fine with me the whole ride to Charleston,” said O’Roak.

Trooper Chris Carr assisted O’Roak at the scene, as did a game warden and the Penobscot County Sheriff’s Department.
