A WOMAN who changed her mind at the last moment about committing suicide was critically injured when she set off an explosion in her Sheung Shui home. Three other women were hurt in the blast at the woman's 11th floor flat in Tsui Lai Garden at about 11 am. The windows were blown out and the flat badly damaged. Two neighbours who helped pull the badly burnt 35-year-old woman from the blaze said she told them she had changed her mind at the last minute. ''She told me she wanted to kill herself and had cut the plastic pipe [of the liquified petroleum gas canister] in the kitchen,'' said neighbour Tsang Tong Lai-fan. She said the woman decided to turn off the gas switch, but this was when a fire started. ''She told us she did not want to die and repeatedly asked us to forgive her for causing so much trouble,'' she said. Neighbour Choi Lai-fong said: ''Her front door was blown off and the home was in bad shape. Parts of her skin had been burnt off, but she was conscious.'' The woman was in critical condition in intensive care in the Prince of Wales Hospital. A neighbour, 53, identified as Mrs Lee, was in fair condition after suffering cuts from broken glass while she was hanging clothes on her balcony. Two other neighbours, aged 29 and 76, were treated for minor injuries and discharged. It took an hour to put out the fire. Police said 41 people were rescued by firemen. The building was blocked off last night. A 17-month-old girl, Yung Hoi-shan, who had been left alone in an 18th floor flat for three hours during the fire, was rescued by policeman and reunited with her father.
