(Spokane Valley, WA) -- A Spokane Valley teenager has first-hand experience with one of the hazards associated with playing Pokemon Go. The 17-year-old told KHQ-TV he and his friend were playing the game Friday night at Greenacres Baptist Church when they heard footsteps from behind. The teen says he was grabbed by the collar, punched in the back of the head, and pushed to the ground. The teen suffered minor injuries. There's no word on a description of the attacker, who ran away when a Good Samaritan stopped his car nearby and honked his horn.
