Alleged unlawful Columbus casino conduct outlined November 28, 2012 at 3:01 am COLUMBUS, Ohio (AP) – Ohio authorities plan to share the results of a monthlong investigation into alleged unlawful conduct at the new Columbus casino. Hollywood Casino Columbus opened last month as the third of four casinos opening in the state after voters approved them in 2009. Franklin County Prosecutor Ron O’Brien was scheduled to discuss the probe Wednesday morning along with Karen Huey, director of enforcement for the Ohio Casino Control Commission. O’Brien says the investigation involved the unlawful conduct of numerous patrons. In July, Cuyahoga County announced the state’s first prosecution of alleged casino cheats in a case involving suspects at the Cleveland casino. Copyright 2012 The Associated Press.
