Sports team owner and pizza billionaire Mike Ilitch wants to carve out another slice of downtown Detroit. Officials from Ilitich's Olympia Development company shared plans with state legislators Tuesday to develop a downtown district that would be comprised of residential, retail and office facilities and anchored by "a new state-of-the-art, multi-purpose events center."The new events center could be home to a new hockey arena thought to be in the works for the Detroit Red Wings.The development would create an estimated 5,500 jobs for the events center alone and about 8,300 jobs total, according to an Olympia Development release.
