A Santa Rosa woman was arrested Wednesday after police said she attacked her boyfriend with an aluminum baseball bat.

Shortly after 7 a.m., police were called to a home on the 900 block of Yulupa Avenue in east Santa Rosa. When they arrived, they encountered a man in front of the home who said his girlfriend struck him with a bat during an argument, Santa Rosa police said.

The man, who refused medical treatment, identified the woman as Laura Pontes, 52, and told officers she was in the home, police said. He also said there were guns and a child inside.

Police said they tried for several hours contacting Pontes by phone and social media, as well as through a patrol vehicle’s PA system. Pontes eventually went to the rear door of the home, where she was arrested.

Police said the boy in the house was unharmed and placed with relatives. Pontes was booked into Sonoma County Jail on suspicion of bodily injury to a spouse and assault with a deadly weapon.
