SINGAPORE, Nov 7 — A 22-year-old Singaporean man was today sentenced to nine months’ jail for slashing local actor Ryan Lian outside NEX shopping mall in Serangoon after a staring dispute turned violent.

Aaron Samuel Yukon pleaded guilty to causing grievous hurt, while a separate charge of possessing a karambit knife was taken into consideration, Singapore-based news outlet CNA reported.

The court heard that Lian, known for his roles in Ah Boys to Men 4 and Money No Enough 3, was smoking near the mall at about 6.10pm on November 22 last year when Yukon, a stranger, joined him and they began staring at each other.

A fight broke out, during which Yukon reportedly pulled out a karambit knife from his pouch and slashed Lian’s face before fleeing.

Lian suffered facial fractures, cuts and bruises, and was taken to hospital after being treated by off-duty paramedics.

The prosecution sought up to 11 months’ jail, citing the public nature of the attack and the seriousness of Lian’s injuries.

Yukon’s lawyer argued that his client acted in self-defence after being provoked, and noted that he had Attention Deficit Hyperactivity Disorder (ADHD) which affected his impulse control.

ADHD is a neurodevelopmental disorder that affects how a person pays attention, controls impulses, and manages activity levels.

The court sentenced Yukon to nine months’ imprisonment.
