San Francisco mall brawls spark fear as teens clash.

Mobs of teenagers have been involved in violent brawls at the Stonestown Galleria mall in San Francisco, with several incidents taking place from March 15 to March 17. The fights involved groups of juveniles attacking each other or bystanders, with one victim treated at a hospital for non-life-threatening injuries. No arrests have been made. The mall will be increasing its security patrols, but the San Francisco Police Department is 500 officers below where it should be for a city of its size. The police department is working with shopping center officials to assess security measures to address criminal activity.
