DURHAM — A 17-year-old local boy remained in Central Maine Medical Center on Tuesday night after being attacked by a loose bull on his family’s property Monday night.

The boy, whose name was not released, suffered a puncture wound to his back and other injuries after being charged by the bull while helping a group corral the animal after it got loose from its pen. The incident was reported at 6:15 p.m.

Sgt. Tim Kachnovich of the Androscoggin County Sheriff’s Office said the attack occurred on a section of the family’s property that runs along Newell Brook Road. The property is located at 361 Cedar Pond Road and is owned by the boy’s father, Vincent Huntington. Newell Brook Road and Cedar Pond Road intersect.

Kachnovich said the bull’s horn did not puncture any vital organs and that the boy’s injuries were not life-threatening.

“The bull escaped from the pen,” Kachnovich said. “The son was trying to get the bull back in the pen when the bull got uncooperative and struck him with a horn and punctured his back.”

Chief William St. Michel of the Durham Fire Department said the bull charged at people trying to get it back in its pen. He said rescue personnel did not help chase the bull, and that the animal had been killed around the time emergency crews arrived.

“There was a bunch of them trying to get the bull back in its pen,” St. Michel said. “(The 17-year-old) wasn’t the only one charged. He just wasn’t lucky enough to get out of the way.”

The bull was killed by a neighbor who shot it with a rifle.
