Crown shares plunge after China detains high-roller chief

Shares in billionaire James Packer's Crown Resorts plunged on Monday after 18 sales and marketing staff were detained in China, including an executive in charge of luring high-rollers to Australia. The gaming company's stock fell 13.9 percent to close in Sydney at Aus$11.15. It followed news that three Australians were among those hauled in for questioning by Chinese authorities on Thursday and Friday last week, with the company unable to contact them.
