AUBURN — A Greene man accused last year of beating his ex-girlfriend’s boyfriend, threatening him with a rifle, and assaulting her, pleaded guilty Friday to related charges.

An Androscoggin County Superior Court judge on Friday ordered Andrew Breton, 22, formerly of Sabattus, to serve three months of a three-year sentence for aggravated criminal trespass and criminal threatening with a dangerous weapon, both felonies. On charges of assault and domestic violence assault, he was ordered to serve three-month sentences at the same time as the others. He also must pay a $300 fine. Other charges were dismissed.

Breton is expected to turn himself in Friday, July 29, to start serving his sentence.

On Sept. 8, shortly after 9:30 p.m., a 911 call featured people screaming and running down Church Street in Livermore Falls, also known as Route 133. As a Livermore Falls officer responded to that area, a report of a domestic violence assault on Munsey Avenue was received by police. The officer went to Munsey Avenue and found people returning to the home and the assailant gone, police said.

Both victims had identified Breton as the assailant, police said.

According to a police report, Breton entered the home of his ex-girlfriend and started beating her boyfriend. Breton threatened the man with a rifle he had grabbed at the house. The gun had a loaded clip in it, but there was no bullet in the chamber, police said.

The woman tried to distract Breton so her boyfriend could get away, but Breton hit her, grabbed her by the throat and placed her against a wall, police said.

The boyfriend tried to leave the house several times, but Breton stopped him until finally the woman cornered Breton.

Breton was found later that night in Sabattus and arrested.

The male victim in the case had been taken to a Farmington hospital by ambulance, police said.

After serving his sentence, Breton will be on probation for two years, according to court documents. During probation, he’ll be barred from having any dangerous weapons, including firearms. He’ll be required to undergo a psychological evaluation and counseling for anger and violence issues and complete a certified batterers’ intervention program.

He also must have no contact with his ex-girlfriend and her boyfriend.
