The wife of a Sun Hung Kai Properties tycoon was warned by police after an altercation with a member of the cabin crew during a Cathay Pacific flight from Japan to Hong Kong on Sunday night. A police spokesman said a dispute between a female passenger and a member of the crew over the storage of luggage prompted the pilot to call police after the aircraft landed at Chek Lap Kok. The police spokesman did not identify the passenger. The dispute was later settled but police issued a verbal warning. However, a spokeswoman for Sun Hung Kai Properties said Helen Kwok, the wife of vice-chairman and managing director Raymond Kwok Ping-luen, had a headache during the flight and needed some medication. She said that Mrs Kwok had a misunderstanding with the crew and that the incident had now been resolved. The company spokeswoman would not confirm whether police were involved.
