THREE more Hongkong Bank employees trapped in an arson attack on the Shekkipmei branch last week died yesterday, lifting the death toll to eight. Supervisor Au Wai-ming, 30, died at 10.11 pm in Kwong Wah Hospital. Her colleague Lee Suk-yee, 33, was certified dead at 6.40 pm while manager Lee Chi-wan, 56, died at 7.05 am at the Caritas Medical Centre. All had suffered smoke inhalation and been in a coma since the attack. Two other male and two female bank employees remain unconscious at the Kwong Wah Hospital and the Caritas Medical Centre. Another woman, Mui Yin-yee, 32, has improved and her condition was described as satisfactory. A 32-year-old man, Chu Po-kwong, last week appeared in court on arson and murder charges relating to four bank staff who had died within 24 hours of the attack. Police said additional charges would likely be laid when he appeared in court again. Lee Chi-wan's brother, Gordon, 58, who is a bank manager at the Un Chau branch of the Hongkong Bank, said: ''We were hoping for a miracle to happen, but he died. Nonetheless, everyone tried their best. We are sorry for those who died.'' Mr Lee said staff at his branch had begun a fire safety awareness campaign. Unlike the Shekkipmei branch, the Un Chau branch has a fire exit. Lau Yuet-hon, brother-in-law of the dead man, said he was seeking legal advice on who was accountable for the tragedy. He said he doubted claims that the bank met all local fire safety requirements. Lee Chi-wan left a wife aged 51, a 29-year-old son and two daughters aged 22 and 23. Lee Suk-yee, who had a one-year-old son and a daughter aged four, had worked with the bank for more than 10 years and had been transferred to the Shekkipmei branch just a month before the tragedy struck. Mr Au had a three-year-old son and started as a teller 10 years ago. He was recently promoted to supervisor. Yesterday, about 100 people including many bank staff paid their last respects to another victim, Tsang Liu Pui-kei, at Hunghom's Universal Funeral Parlour. Tsang, 26, who was pregnant, was certified dead on arrival at hospital after the attack. Hongkong Bank chairman John Gray and executive director Paul Selway-Swift were among 40 to 50 bank staff who attended the ceremony. Legislator Vincent Cheng Hoi-chuen, a senior bank staff member, was also present.
