Christopher Bjerkness, 31, was arrested in Duluth, Minn., in July and charged with another episode of breaking into a gym facility and slashing numerous large rubber exercise balls. He had acknowledged a sexual urge to slash that type of ball following a conviction in 2006 for cutting up 70 balls in three incidents at the University of Minnesota Duluth. This time, 40 balls were damaged at a St. Mary's/Duluth Clinic West building. Police were told by a psychologist last year, after Bjerkness abandoned court-ordered therapy, that he "continues to be a risk to society."Duluth News Tribune
