Doctors and family threw a veil of secrecy yesterday over the health and the whereabouts of Stanley Ho Hung-sun. But the scrum of journalists and cameramen outside the Hong Kong Adventist Hospital and the stream of relatives who filed into the Happy Valley facility left little doubt the 87-year-old had been admitted for treatment. For what the gambling and property tycoon was being treated, no one was saying. He was reportedly admitted to the nearby Hong Kong Sanatorium and Hospital last week before being transferred to Adventist. At 8pm, Pansy Ho Chiu-king, managing director of the family holding company Shun Tak Holdings, was seen entering the hospital in Stubbs Road via the back door. Five minutes after that Mr Ho's son Lawrence Ho Yau-lung and his wife walked through the front entrance. Ms Ho and the couple left at 10.35pm without answering reporters' questions. Another of Mr Ho's daughters, Shun Tak deputy managing director Daisy Ho Chiu-fung, visited the hospital separately. Stanley Ho was last seen in public last Tuesday, when he was named founding president of Macau's casino chamber. He missed Sunday's official opening of the Hotel Lan Kwai Fong in Macau. The casino in the hotel is owned by his casino company, Sociedade de Jogos de Macau. Neither Shun Tak Holdings nor Hong Kong Adventist Hospital would comment on earlier reports that the hospital had admitted Mr Ho. In 2007, Hong Kong Sanatorium doctors treated Mr Ho for a rectal injury he sustained while being treated in Bangkok for constipation. He emerged denying he had cancer or had to cut back on his public duties.
