NEWPORT, Maine — Police apprehended a 14-year-old boy who allegedly threatened his foster parents with a knife, said Newport police Chief Leonard Macdaid.

At around noon on Tuesday, police received a call from foster parents on the Durham Bridge Road, Macdaid said.

“They had locked themselves in a bedroom because of this person they’d been taking care of,” he said. “[The teen] was using the knife in a threatening manner. The couple was scared.”

The teen did damage to the house before fleeing on foot. He was apprehended about three hours later and four miles away near the Stetson Road, where a woman spotted the boy on her lawn and called police.

“Anytime a member of the public helps us, we can’t thank them enough,” Macdaid said.

The boy was on probation and will likely be taken to Mountain View Youth Development Center in Charleston, he said. Macdaid said he doesn’t expect any charges to be filed.

Maine State Police assisted with a K-9 unit and an airplane, which happened to be in the area, he said. Dexter police also assisted.
