A human rights group yesterday urged the government and a school to look into and explain publicly the suicide of a young psychosis patient who jumped from a school building on Monday. The death of Wong Ling-fung, 17, who was diagnosed with psychosis two years ago and who jumped from a staircase at Tung Chung Catholic School in front of 600 teachers and students, revealed there had been little social assistance for pupils with psychological problems. Human Rights Monitor's director Law Yuk-kai urged the school to investigate if anyone had forced Wong to take medicine in front of teachers, as the boy's father had told police on Tuesday. The father has asked police to investigate what happened in the 15 minutes after Wong took the medicine and before he jumped, and why the school had the right to force his son to take medicine. Dr May Lam Mei-ling, a member of the Early Psychosis Intervention Society, said some psychosis patients were unwilling to take medicine in front of others. 'This can unnecessarily expose their illness and create a stigma for them, causing discrimination,' she said. A police spokesman said they would look into everything that had happened to Wong after he returned to school. 'Up to this stage, police are treating the case as suicide and there are no suspicious circumstances in the incident,' the officer said. A spokesman for the Education Bureau said it had not issued any direction for teachers on how to take care of pupils with psychosis, but it encouraged schools to communicate more with parents of those suffering from mental illness. A spokesman for the Social Welfare Department said some district task groups, which hold regular meetings with non-governmental organisations, social workers and psychiatrists to explore assistance to mental patients, had been set up after the chopping spree in Kwai Chung earlier this month, in which a man with a mental disorder killed two and injured three. The incident had also prompted the Hospital Authority to set up a seven-member committee to review its management and follow-up of mental patients. The committee is to be chaired by Professor John Leong Chi-yan, Open University president and governing committee member at Castle Peak Hospital, Tuen Mun. Last night, Wong's father, classmates, Christians from different churches and Tung Chung neighbours were among about 100 people attending a memorial service held at Yat Tung Shopping Centre. Organiser Reverend Patrick So Tat-wing said he hoped the event could bring peace, enthusiasm and caring to the neighbourhood. Education lawmaker Cheung Man-kwong said the case revealed fault in the Education Bureau, which he urged to assist schools to understand more about students with mental illnesses. Training courses on handling those students should be provided to teachers.
