Three women police say burst into a Skowhegan apartment where they beat a woman with their fists and threatened her boyfriend with a baseball bat have been arrested. Deputy Chief Dan Summers says the suspects went to an apartment in town just before midnight Monday, apparently angered about a related theft. Summers says they banged on the door with a bat and rushed in when the woman opened it. He tells the Morning Sentinel, they grabbed the woman by her throat and threw her against the wall. Two started punching her while a third watched. Summers says it’s “unusual” for women to be involved in a home invasion. Arrested were 33-year-old Stacey Lynn Robinson: 28-year-old Kristina Santamore: and 34-year-old Brandy St. Pierre. It was not clear if they had lawyers.
