The fire broke out at 2.55am at a flat at 927 Canton Road. The Fire Services Department mobilized about 50 firefighters, along with nine fire engines and two ambulances due to the blaze, with the blaze being put out in about an hour.

The woman, aged 36, was found unconscious at the scene and was rushed to Kwong Wah Hospital for resuscitation. She was later declared dead at 4.25am.
