German fashion giant Hugo Boss AG and the former heads of its US operations, Marty Staff and Vincent Ottomanelli, have been issued with class action lawsuit amid allegations they mislead investors. Munich-based lawyers Rotter Rechtsanwaelte said in a news release that it and New York-based law firm Shalov Stone and Bonner planned to sue on behalf of investors who had held either common shares or preference shares in Boss between November 5, 2001 and May 28, 2002.
