Man admits to jumping on backs of student athletes (AP) - A 250-pound man with a history of jumping on the backs of student athletes in the Pacific Northwest has pleaded guilty to assault. The Independent Record (http://bit.ly/zS4tib) reports 28-year-old Sherwin Shayegan acknowledged in court Wednesday that he hopped on two players at a soccer tournament in Helena in October. He pleaded guilty to two misdemeanor counts of assault. Last spring, the Oregon School Activities Association warned athletes to look out for Shayegan after he turned up at events in Eugene and Pendleton and got piggyback rides from some athletes. Police in Bonney Lake, Wash., say he gave money to an athlete and jumped on his back. Judge Bob Wood gave him a 360-day suspended jail sentence, fined him $730 and told him to "go back to Seattle and behave."
