Tsui Po-ko

Tsui Po-ko (Chinese: 徐步高) (17 May 1970 – 17 March 2006) was a police constable of the Hong Kong Police Force, bank robber and serial killer. He is one of Hong Kong's most well known serial killers. He was killed during an ambush on two police constables in a Tsim Sha Tsui subway which led to a shootout. The inquest into the events leading up to his death aroused great interest in Hong Kong, as it unravelled a string of intriguing events, and revealed the secret life of a policeman with a delusional state of mind. On 25 April 2007, the five-person jury in the coroner's court unanimously decided that Tsui was responsible for injuring one and killing two fellow police officers and a bank security guard, on three occasions. The jury returned a verdict that he had been "lawfully killed" by fellow officer Tsang Kwok-hang in a shootout. The inquest lasted 36 days, one of the longest ever inquests in Hong Kong. Assistant Police Commissioner John Lee said that this was "an exceptional case", while the case's coroner called it "the most difficult" inquest for a jury he had ever encountered.
