Fatal love triangle: when a Hong Kong policeman stabbed a fellow police inspector to death, and was himself badly wounded, over the Thai girlfriend they shared
- A knife fight over a married Thai woman between two Hong Kong policemen in 1984 left one dead and the other seriously wounded
- A 26-year-old was certified dead at the scene, while a 24-year-old was sent to hospital and later charged with murder. A jury found him not guilty

“A British police inspector died of stab wounds and another was seriously injured at a Mid-Levels flat yesterday afternoon after a row about a Filipino girlfriend,” reported the South China Morning Post on August 29, 1984.
“Inspector G.A. Dallas (26), who had chest stab wounds, was certified dead at the scene by a police pathologist. And Inspector J.N. Davison (24), who had stomach stab wounds and cuts on his hands, was taken to Queen Mary Hospital, where his condition was fair last night.
“Police found the body of Insp Dallas in a pool of blood after Insp Davison, who was covered in blood, collapsed on opening the door of his sixth-floor flat at around 2.45pm. Their families in Britain are expected to be informed today and a post-mortem will be carried out.
“Insp Davison is believed to have phoned the police to report the tragedy in the Hermitage building at 42 Kennedy Road – a block of Government flats mainly for expatriate single officials.”


On July 4, 1985, the Post wrote that Davison “was yesterday found not guilty of [murder] in a violent struggle at the Hermitage on August 28 last year. Insp Dallas was stabbed five times. Insp Davison claimed the wounds were inflicted in self defence.
