Chua Jing Yuan, 27, was jailed for 5½ years after he randomly attacked a woman at Kallang Wave Mall with a knife.

He heard voices telling him to kill someone and himself, then bought black clothes, bleach and weapons before going to the mall to find a target.

The victim survived neck and chest wounds. Prosecutors sought seven years' jail. The defence asked for a prison term of not more than three years.

SINGAPORE – After he heard a voice telling him to kill someone and commit suicide, a man armed himself with a knife and a claw hammer, and went to Kallang Wave Mall to look for a target.

After wandering around for close to an hour in the early hours of July 14, 2025, Chua Jing Yuan randomly attacked a woman with the knife , slashing her neck and stabbing her in the chest. She survived.

On Nov 2, Chua, 27, was sentenced to 5½ years’ jail after he pleaded guilty to a reduced charge of attempted culpable homicide with hurt caused to Choong Wen Ting, who was then 29 years old.

Two charges for possessing offensive weapons in public were considered during sentencing.

Chua was originally charged with attempted murder.

He was later assessed to be suffering from major depressive disorder with psychotic features, which diminished his mental responsibility for his acts.

Deputy Public Prosecutor Grace Chua told the High Court on Nov 2 that Chua was first seen at Jurong Polyclinic in 2021 for anxiety.

He was referred to Ng Teng Fong General Hospital, where he was diagnosed with generalised anxiety disorder with obsessive compulsive symptoms.

Chua defaulted on his treatment after his last appointment in March 2023.

Over the next two years, his mental state deteriorated. He reported hearing a voice telling him to kill someone and to commit suicide by drinking bleach, said the prosecutor.

On July 13, 2025, Chua decided to act on the instructions of the voice, which also insisted that he dress in black.

He bought black clothing and shoes, a black backpack, black face masks, gloves, a bottle of bleach, a claw hammer and a kitchen knife.

Chua then packed the items into the backpack and changed into his new clothes and shoes. He took a photo of where he stored his belongings so that his family could find them.

At about 12.30am on July 14, he arrived at Kallang Wave Mall, and put on a face mask.

Meanwhile, the victim was having drinks with her boyfriend and an acquaintance at a bar in the mall.

At about 1.20am, she was outside the restroom when Chua stopped her, telling her in Mandarin to “wait a moment”.

He took out the knife and targeted her neck and chest as he believed it was the fastest way to kill her.

Chua then fled but tripped and fell after exiting the mall. He was restrained by the victim’s boyfriend and acquaintance, who gave chase after spotting him.

During the struggle, the bottle of bleach and the knife fell out of his backpack.

Other passers-by helped to subdue Chua and call the police.

When he was arrested, Chua repeatedly demand ed that the police officers shoot him, and also threatened to kill himself.

The victim was taken to Tan Tock Seng Hospital, where she underwent surgery.

She suffered a 5cm stab wound to the right side of her chest which cut into muscle, and a 6cm slash to her neck that cut the external jugular vein without injuring any major nerve or vital blood vessel.

She was discharged the next day.

A medical report stated that the neck injury could have been fatal if there had been massive blood loss.

The prosecutor sought seven years’ jail, arguing that beyond acting on the broad instructions of his auditory hallucinations, Chua had planned and carried out the attack with systematic deliberation.

She added that he had attacked a stranger in a public place of recreation, with the intent to kill.

“The attack was wholly senseless. Any member of public could have been the accused’s target,” she said, adding that such attacks can cause significant public disquiet.

Defence counsel Choo Yean Lin asked for a jail term of not more than three years, emphasising that her client was suffering from a severe mental condition that significantly contributed to his offence.

She added that he is currently undergoing treatment in prison for his mental conditions, and had paid about $2,500 to the victim for her medical expenses.

27岁的蔡景元因在加冷购物中心持刀随机袭击一名女子而被判入狱5年半。

他听到有声音告诉他要杀人然后自杀，然后买了黑色衣服、漂白剂和武器，之后去商场寻找目标。

受害者颈部和胸部中弹，但幸存下来。检方要求判处七年监禁，辩方则请求判处不超过三年的监禁。

新加坡——一名男子听到一个声音告诉他要杀人然后自杀后，他带着刀和羊角锤前往加冷购物中心寻找目标。

2025年7月14日凌晨，蔡景元在街上游荡了近一个小时后，随机持刀袭击了一名女子，割伤了她的脖子，并刺伤了她的胸部。该女子幸存了下来。

11月2日，27岁的蔡某承认犯有过失杀人未遂罪，并致29岁的钟文廷受伤，被判处5年半监禁。

在量刑时，考虑了两项在公共场所持有攻击性武器的指控。

蔡某最初被控谋杀未遂。

后来经评估，他患有重度抑郁症并伴有精神病性症状，这削弱了他对自己行为的精神责任能力。

副检察官 Grace Chua 于 11 月 2 日向高等法院表示，Chua 于 2021 年首次因焦虑症前往裕廊综合诊所就诊。

他被转诊至黄廷方综合医院，在那里他被诊断出患有伴有强迫症状的广泛性焦虑症。

蔡先生在 2023 年 3 月最后一次就诊后便未继续接受治疗。

在接下来的两年里，他的精神状态恶化。检察官说，他声称听到一个声音指示他杀人并喝漂白剂自杀。

2025年7月13日，蔡先生决定按照那个声音的指示行事，那个声音还坚持让他穿黑色衣服。

他买了黑色衣服和鞋子、黑色背包、黑色口罩、手套、一瓶漂白剂、一把羊角锤和一把菜刀。

蔡先生随后将物品装进背包，换上了新衣服和鞋子。他还拍了一张存放物品的照片，以便家人能找到它们。

7月14日凌晨12点30分左右，他抵达加冷波浪购物中心，并戴上了口罩。

与此同时，受害者正在商场的一家酒吧里和她的男友以及一位熟人喝酒。

凌晨 1 点 20 分左右，她站在洗手间外面，蔡女士拦住她，用普通话说“等一下”。

他掏出刀，瞄准她的脖子和胸部，因为他认为这是杀死她的最快方法。

蔡某随后逃跑，但在离开商场后绊倒摔伤。受害者的男友和熟人发现他后追赶上来，将他制服。

搏斗中，漂白剂瓶和刀子从他的背包里掉了出来。

其他路人帮忙制服了蔡某，并报警。

蔡某被捕时，多次要求警察开枪打死他，并威胁要自杀。

受害者被送往陈笃生医院，并在那里接受了手术。

她的右胸被刺伤 5 厘米，伤及肌肉；脖子被割伤 6 厘米，割断了颈外静脉，但没有伤及任何主要神经或重要血管。

她第二天就出院了。

一份医疗报告指出，如果颈部受伤导致大量失血，后果可能不堪设想。

检察官寻求判处蔡某七年监禁，理由是蔡某除了按照幻听的大致指示行事外，还经过系统性的深思熟虑策划并实施了袭击。

她补充说，他曾在公共娱乐场所袭击一名陌生人，意图杀人。

“这次袭击完全是无意义的。任何公众成员都可能成为被告的目标，”她说道，并补充说，此类袭击会引起公众的极大不安。

辩护律师朱燕琳请求判处不超过三年的监禁，并强调她的当事人患有严重的精神疾病，这极大地影响了他的犯罪行为。

她补充说，他目前正在监狱接受精神疾病治疗，并已向受害者支付了约 2500 美元的医疗费用。
