4400 BLOCK ALISON AVENUE: A 41-year-old woman was arrested for domestic battery after getting into a fight with her 16-year-old son Friday evening. The boy reported his mom punched him in the head, bit his arm and scratched the inside of his cheek following an argument. As he was being attacked, he grabbed her wrist and pushed her face away in self-defense, he said. The woman said the two argued and fought. She was unsure who started the fight, but felt she was acting in self-defense when she bit him and scrapped his cheek in a “fishhook-like manner.” She had scratches to her left wrist that appeared to be defensive wounds, but appeared to have been the primary aggressor. Both parties refused treatment. No reason was given for the argument, Police Sgt. Dean Welch said.
