Tsui Po-ko (Chinese: ???) (17 May 1970 – 17 March 2006) was a police constable in the Hong Kong Police Force who was implicated in a number of crimes, including bank robbery and murder.
He died when he and another police constable shot each other in a gun battle in a Tsim Sha Tsui subway.
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 separate 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".
Coroner Michael Chan Pik-kiu called it "the most difficult" inquest for a jury he had ever encountered.
