A drug rehabilitation school on Lantau hopes the clearing of corruption allegations can help it move to a Mui Wo site and get the green light to open senior secondary classes. Christian Zheng Sheng College on Sunday claimed the city's anti-graft agency had cleared the school of allegations of corruption and malpractice late last month. The college was embroiled in a string of allegations over its operations in August last year. The Independent Commission Against Corruption launched an investigation into the school over its use of funds and accounts following a complaint. The college's principal, Alman Chan Siu-cheuk, told RTHK yesterday the end of the investigation was cheering news to the school. He hoped the school could operate these classes in September to enable students now in Form Three to continue in a formal education at the college. Education authorities require there to be at least three Form Four classes at a school to give students a range of subject options. The school has only two classrooms. Chan added that the college had to upgrade its classrooms and teaching facilities. He said it would be hard to do so at the present site in a remote part of Lantau given its limited space. Professor Daniel Shek Tan-lei, chairman of the Action Committee Against Narcotics and a former college supervisor, said another option was a thorough renovation of the present campus. But Chan said a vacant school site in Mui Wo would be the best location because it was near the present campus and immediately available.
