A hospital declared a man mentally stable a few hours before it again diagnosed him – as schizophrenic – but by then he had chopped a security guard to death, a court heard on Thursday.

Wong Pat-tat, 54, hacked to death security guard Lee Kai-kwong, 57, with a chopper at Choi Wah House, Choi Yuen Estate, in Sheung Shui, on January 30 last year.

On Thursday Wong pleaded guilty to manslaughter in the Court of First Instance.

Before the killing, Wong hallucinated that he was seeing ghosts and had delusions that his wife had been killed by Lee, the court heard.

On the night of the fatal attack, Wong’s wife called the police at 3.30am after Wong kept knocking on doors and making noises with kitchen utensils, prosecutor Richard Wong Tat-wah told the court.

The wife was aware of Wong’s mental illness, the court heard. Wong was taken to North District Hospital at about 4am, but was diagnosed as mentally stable and discharged, the prosecutor said.

But about three hours later, Wong left his home and went to the guard post three floors below his flat.

He attacked Lee with a chopper, the court was told. Lee tried to flee, falling down a flight of stairs.

Wong caught up with him and kept chopping the victim, who died at the scene. Wong’s family called police.

After his arrest, Wong was taken back to North District Hospital, where he was diagnosed with schizophrenia.

Mr Justice Alan Wright adjourned sentencing to next Thursday.
