Five people will appear in court this morning on murder charges following Saturday's suspected triad firebomb attack on a Tsim Sha Tsui karaoke lounge which killed 16 people.
The three men and two women, aged between 17 and 27, are all alleged members of the Sun Yee On triad society.
They will appear at South Kowloon Court.
The charges were laid just a few hours after the blaze claimed its 16th victim, amateur photographer Hui Chi-wah, 24, who died in Queen Elizabeth Hospital at 4.54 pm yesterday.
Two more men, aged 28 and 25, have been detained for further questioning but have not been charged.
As the five were being formally charged, Organised Crime and Triad Bureau (OCTB) investigators swooped at the China border and arrested a Sun Yee On dai lo (big brother) who they believe may have knowledge of the firebombing.
