Korean Air 'water rage' heiress suspended, faces criminal probeA Korean Air heiress accused of assault has been suspended by her father's company as police Tuesday launched a criminal investigation into claims she threw water into a man's face in a business meeting. Cho Hyun-min, a marketing executive at the South Korean flag carrier, is the latest scion of its founding family to spark controversy through her hot-tempered behaviour. Four years ago her older sister Cho Hyun-ah made global headlines for angrily kicking a cabin crew member off a plane after being served macadamia nuts in a bag rather than a bowl -- an incident quickly dubbed "nut rage".
