Two executives of property giant Wharf (Holdings) were among 10 people arrested in the past two days by anti-graft officers over an alleged multi-million dollar construction bribery scandal. The pair, a senior manager and a project manager, were alleged to have solicited and accepted bribes from construction companies, the Independent Commission Against Corruption said yesterday. The others arrested are the managing director of an engineering consultancy firm, a director of a trading company and six directors of four construction companies. The ICAC said the alleged bribery cases were related to a number of Wharf's commercial and residential construction projects. A source said last night that the projects included the luxury Galaxia residential development in Diamond Hill. The ICAC said the probe came after a complaint by Wharf. The anti-graft agency alleged that the senior manager had taken bribes from the construction companies' directors in return for his assistance in releasing tendering information, securing contracts and certifying contract payments. The 10 were still being detained at the ICAC headquarters in Central early this morning. Wharf, the main operating arm of blue-chip Wheelock, was unavailable for comment last night.
