Former Sun Hung Kai Properties chairman Walter Kwok Ping-sheung became "suspicious" and made several "false accusations" against family members and company executives after being freed by abductors in 1997, the Court of First Instance heard yesterday.
Kwok's demeanour was described by SHKP executive director Mike Wong Chik-wing, a witness in the corruption trial of Kwok's two brothers and former chief secretary Rafael Hui Si-yan.
"When he first returned to the office, he was very slow and found it difficult to concentrate," Wong said. "Later on, he became very active and worked very hard, but then he also started to become suspicious of others."
SHKP co-chairmen Thomas Kwok Ping-kwong and Raymond Kwok Ping-luen are accused with two others of funnelling tens of millions of dollars to Hui to be the developer's "eyes and ears" in the government. Walter Kwok is not charged.
Barrister Clare Montgomery QC, for Thomas Kwok, asked Wong if the abduction had a negative impact on Walter Kwok's health and personality.
She asked if Walter Kwok had become "suspicious about his brothers" and made several "false accusations" since 2002.
"Yes, it did happen," Wong said. "It happened to me in May 2008 and I observed other cases in which he made false accusations against the others."
Montgomery asked Wong about two accusations between 2002 and 2003.
In one, she said, Walter Kwok accused Thomas Kwok's wife, Ingrid Kwok, who worked in SHKP's material supply department, of improper purchasing procedures. In another, she said, Walter Kwok alleged that Sun Hung Kai executive Thomas Chan Kui-yuen - a defendant in the case - had improperly handled some land sales.
Wong said both accusations were false.
Wong, a trained surveyor, said he was responsible for the technical development of land and design for the company's Ma Wan residential project and the West Kowloon Cultural District.
Montgomery asked Wong if SHKP had any "eyes and ears" in the government or if the developer received any "inside information" from the government on these projects. "I personally did not hear any inside information from the government," Wong replied.
Hui, 66, faces eight counts related to bribery and misconduct in public office. Thomas Kwok, 62, faces one charge of conspiracy to offer an advantage to Hui and two counts of conspiracy to commit misconduct in public office. Raymond Kwok, 61, faces four charges, including one with Hui of furnishing false information. Thomas Chan and former Hong Kong stock exchange official Francis Kwan Hung-sang each face two charges. All plead not guilty.
The trial continues.
