An independent inquiry into Hong Kong's deadly Tai Po fire has concluded after months of investigation, blaming a series of failures for the blaze that killed 168 people. The panel, led by Justice David Lok Kai-hong, wrapped up its hearings on Friday. The proceedings began on March 19 and included 30 public sessions. Investigators examined more than one million documents and heard testimony from 80 witnesses. The fire occurred at the Wang Fuk Court housing estate. It is one of the deadliest fires in Hong Kong's history. The inquiry's findings pointed to multiple shortcomings in safety measures and emergency response. The panel did not single out one cause but said a combination of failures led to the high death toll. The report will be submitted to the Hong Kong government. Officials have not yet announced when the findings will be made public. Families of the victims have been waiting for accountability and answers. Many hope the recommendations will prevent future tragedies. The inquiry faced some delays due to the large volume of evidence and the complexity of the case. Justice Lok praised the work of the inquiry team and the cooperation of witnesses. The fire raised widespread concern about building safety standards in the city.
