A biker gang leader was arrested in Colorado on a tip three days after a carefully rehearsed raid by federal marshals missed him, officials said. Marshall \"Big Bo\" Fry, a member of the Wheels of Soul, was the last of 18 bikers indicted by a federal grand jury in Missouri in June to remain at large, the Denver Post reported. He was captured Tuesday night on a street in Aurora. The early morning raid on a Denver auto repair shop Saturday just missed Fry, investigators said. \"He knew we were looking for him,\" Charlie Ahmad of the U.S. Marshals Service said. Fry faces charges that include racketeering, attempt to commit murder in aid of racketeering and conspiracy. He allegedly was involved in a shootout with the Hell\'s Lovers gang in Denver and an attempt to kill leaders in the Outkast gang in East St. Louis, Ill. Wheels of Soul is headquartered in Philadelphia with chapters in other cities, investigators say. They describe it as a violent gang involved in dealing crack cocaine and using homicide to maintain its turf.
