A former primary school principal is to appear in court today after an investigation found he allegedly awarded HK$250,000 worth of school works projects to his brother's companies. So Yau-hang, 55, the former principal of Yan Oi Tong Tin Ka Ping Primary School, faces one count of misconduct in public office. He is jointly charged with his brother, So Yau-cheong, 53, and Ma Sai-tong, 42, a teacher, with one count of conspiracy to defraud. The suspects will appear before Kwun Tong Court this morning to enter a plea. The Independent Commission Against Corruption, which investigated after a complaint, revealed the alleged offences yesterday. The alleged offences occurred between June 2001 and November 2006. The ICAC said So Yau-hang, the principal of the school, arranged for quotations from four companies - all related to his younger brother - for maintenance, renovation or other services. It was alleged that 10 job orders, including the installation of a microphone and air conditioners in the school hall and the cleaning of ventilation fans, were awarded to the brother's companies. The job orders were worth about HK$150,000. The principal allegedly failed to declare to the school his relationship with his brother in accordance with government guidelines. The conspiracy charge claimed that in April 2006 the trio conspired to defraud the school by falsely representing that Wan Kee Engineering Co submitted the lowest bid in the tendering exercise for a school renovation contract. A HK$105,000 contract was awarded to the company. ICAC inquiries revealed that Wan Kee's original bid was allegedly the highest among five contractors. The three allegedly arranged for the company to submit a second quotation, which became the lowest bid. The defendants had been granted ICAC bail, pending their court appearance today.
