At about 3.20 pm on Tuesday, 8th January, 1974 Senior Constable Curson was standing on the steps at the main entrance to Flinders Street Railway Station talking to a newspaper seller. Whilst they spoke a young woman came up and spoke to the Constable, who turned towards her. At that moment, James Henry Belsey, walked up behind him, produced a knife, and cut the policeman's throat. As Curson slumped to the footpath, Belsey calmly walked away, crossed Flinders Street and entered Young & Jackson's Hotel. He was arrested a short time later. Meanwhile, Curson had been removed to Prince Henry's Hospital with a massive wound to his throat and died two hours later. It was later learned that Belsey had a lengthy history of mental disorder, and had frequently threatened to kill a policeman. He was charged with Curson's murder but acquitted on the grounds of insanity, and was then sentenced to be detained at the Governor's pleasure.
