Crimes under psychosis

February 2014

A 33-year-old man with a psychotic disorder hit his mother repeatedly on the head, and taped her mouth shut. All this after she quizzed him about his bad attitude on the phone.

In a 2½-hour long ordeal, he grabbed her hands, slapped her and punched her on the head. He then pulled her by the hair into his bedroom, sat on her and continued to punch her. He also pulled her mouth sideways to stop her from shouting for help.

The man was jailed 26 months, but was spared caning due to his psychotic disorder.


A Turkish national at Changi Airport was waiting to catch a flight to Istanbul when he spread the word that a plane getting ready for take-off would blow up.

He then attacked an airport auxiliary police officer who tried to calm him down. The police had to use force to subdue him.

About two days before he arrived here from Australia, the man had taken amphetamine, methamphetamine and cannabis, which gave him hallucinations and made him delusional. He was fined $1,000 and sentenced to a month in jail.

MARCH 2007

A man went on a rampage at home, swinging a 30cm-long chopper and an axe while claiming he had seen "people" at his rented flat.

After accidentally injuring himself, he dashed out of the house - bare-bodied and carrying the chopper and axe. He was later charged in court and taken to the Institute of Mental Health (IMH) for psychiatric assessment.

The man developed a high fever and was taken to Changi General Hospital where he died the next day.
