The man convicted of shootings during the 2010 Indiana Black Expo Summer Celebration that left at least nine people wounded in downtown Indianapolis was arrested Wednesday night after a police chase on the city’s northwest side. Shamus Patton, 20, and two other men were taken into custody after the pursuit. Police said it began with an attempted traffic stop. When the chase ended at 25th Street and Falcon Drive, police discovered two guns in the vehicle. Patton was sentenced to eight years in prison for aggravated battery after the IBE shootings. He was scheduled to be released from the Indiana Department of Corrections in mid-July, but was being housed in a community transitions unit after serving only two years, eight months and 30 days.
