A 54-year-old Petaluma man has been arrested for assaulting another person with a metal pipe unprovoked. It happened last Thursday evening at Steamer Landing in Petaluma with police responding within minutes to find Joseph Anderson still attacking the victim but without the pipe. Anderson eventually complied with officers commands and stopped allowing for him to be arrested. Officers then searched the area and recovered the metal pipe used in the attack. The male victim was treated for minor injuries at the scene.
