Arson is suspected after fire broke out in an empty hut with no power supply in a squatter area at Diamond Hill yesterday. Three people were injured and 70 made homeless. Firemen said the blaze at Ha Yuen Leng Village was suspicious because the same vacant home went up in flames last month. More than 100 people from 31 households were evacuated yesterday. The second-alarm fire - on a scale of one to five, where five is the most serious - began at 3pm and was put out an hour later. Villagers said they heard several explosions. Two men and a woman aged between 23 to 36 suffered minor injuries and were sent to Queen Elizabeth Hospital. Last night, a man and the woman were still in hospital in stable condition. 'The fire was suspicious because it started in the same unit where a fire on June 11 also started. The unit has no power supply,' a Fire Services spokesman said. Residents, many shoeless, gathered at the Tai Hom Playground for registration and to await resettlement plans. About 106 victims from 31 families registered with the Social Welfare Department, which distributed food and daily necessities. The half-empty Ha Yuen Leng Village used to have a population of 9,000 and was scheduled for demolition last month. But about 900 residents refused to leave, forcing authorities to postpone demolition until later this year. Most of the villagers said they wanted to resettle elsewhere in Diamond Hill.
