THE husband of the elderly woman killed when a restaurant canopy collapsed in Aberdeen said the Government should punish whoever was responsible. Tsui Tak-hung, 85, was speaking after an interim government report identified corrosion as the main reason for the collapse, but said it was too early to blame anyone. Newspaper hawker Mo Yee, 80, was killed and 12 people were injured in the August 1 tragedy. Mr Tsui of Wah Kwai Estate, Aberdeen, said: ''I don't know much about law. But if the law is to protect the good people, the Government should find out who was responsible for the fatal incident.'' He said the Government should not evade this in its investigation. ''It should be a simple case. Either the government department monitoring canopies or the restaurant owner should be held responsible. If it was the restaurant which was responsible, the Government should sue them,'' Mr Tsui said. The report, released yesterday, said rust stains were found on the concrete surface along the broken edge of the canopy, corresponding to the positions of its steel reinforcement. A fish tank built on the top of the canopy had increased the weight on the structure. That could have contributed to the cracking of concrete and the water seeping out of the tank could have caused the corrosion of the steel reinforcement, the report said. Mr Tsui, a retired government cleaner, receives a pension of about $2,000 a month. He was reluctant to talk about the tragedy, but said he missed his wife very much. ''She used to go with me to eat dim sum in the morning and cook for me. Now she cannot be with me and I seldom go to restaurants alone,'' he said. ''Both of us are very old and I was prepared that one day she might leave me. But she was nice and should not have died in an accident.'' Director of Buildings Helen Yu Lai Ching-ping told the Legislative Council Lands and Works Panel meeting that the load on the canopy had been increased by layers of surface scree applied to it. The thickness of the scree ranged from 125 millimetres to 250 millimetres - considered excessive in terms of construction practice. Mrs Yu also said the construction of the canopy could have been defective. Other factors leading to the tragedy could have included the strength and characteristics of the construction materials, workmanship, external circumstances and corrosive environmental conditions. Mrs Yu said it would be premature to comment on whether anyone was responsible for the collapse until the investigation was finished next month. The structure of the building itself was safe. Also at the panel meeting, United Democrat legislator James To Kun-sun asked whether there would be an inquest into the cause of the Kwun Lung Lau landslide which killed five people last month. Secretary for Works James Blake said he would relay Mr To's message to the Attorney-General. Legislators also criticised the way the Government assessed whether a slope was dangerous. They said that in the government classification system of slopes, the hazard to the residents living in buildings ''in the immediate vicinity'' of the slope bore more weight than the threat to the pedestrians passing along roads near a slope.
