The former head of surgery of the University of Hong Kong medical faculty is being investigated by the graft buster over some financial arrangements at the school. The case is still under investigating by the Independent Commission Against Corruption, and it is understood that Department of Justice is also working on the case. Professor John Wong, who retired from the department of surgery a few months ago, confirmed yesterday that he was assisting an ICAC investigation into financial arrangements at the school. 'I am assisting an ICAC investigation .... I can't say anything. I have been advised not to comment on this as an investigation is still going on,' he said. Wong stepped down as head of surgery in 2008 after holding the post for 25 years. Some doctors have complained that he held the top post for too long. His post was taken up by liver transplant surgeon Professor Fan Sheung-tat. A person familiar with the investigation said Wong was involved in running a skills development centre at the faculty. The centre, set up in 1996 with a donation from the Hong Kong Jockey Club, also received public donations and sponsorship. It organises training for health care workers. A university spokesman and an ICAC spokeswoman declined to comment on the matter yesterday. In September last year, the faculty's former dean Lam Shiu-kum was sentenced to more than two years in jail for inducing patients to make donations and payments of almost HK$4 million to his company. The university reviewed its financial transactions at the medical faculty after Lam's case.
