A mother and son from Dayton were arrested Wednesday after he allegedly strangled his girlfriend and his mother interfered as police tried to arrest him.

Maine State Police were called to a house on Dyer Road in Dayton on Wednesday after 26-year-old Brian King allegedly kicked in the door of a bathroom, strangled his girlfriend and threatened to kill her, according to police. He then allegedly assaulted his girlfriend’s mother before running out of the house.

As troopers gathered statements from witnesses, they saw King run across the street and into a barn. Troopers surrounded the barn, but King refused to come out, police said.

King’s mother, Sandra King, 56, of Dayton, arrived on the scene during the incident and tried to enter the barn. Police say she would not comply with warnings from troopers to leave the scene and was arrested for hindering apprehension.

Troopers then entered the barn with a police dog and found Brian King hiding under hay in a loft.

Brian King was charged with aggravated domestic violence (strangulation), assault and on an outstanding warrant. He was taken to York County Jail, where he is being held without bail.

Sandra King was taken to the York County Jail and her bail was set at $100.
