A homemade spear made from a wrought iron fence picket was one of the weapons used in a fight among a large group of juveniles at the Ukiah Skate Park over the weekend. UPD officers responded to the scene to find some using baseball bats and knives as weapons. UPD and Mendocino County Sheriff’s officers worked to detain some of those involved in the altercation. One victim was taken to Adventist Health Ukiah Valley. An investigation continues and UPD has increased its presence at the skate park.
