Footage of the attack posted by students to Reddit and RedNote showed the victim, aged 20 and also Chinese, sprawled on the floor, clutching her neck as friends desperately called for help. Other students restrained the suspect, who was still holding a knife, until authorities arrived.
Subang Jaya police confirmed that the victim had suffered a slash wound to the left side of her neck but said she was in a stable condition.

“She was taken to the emergency unit of University of Malaya Medical Centre (PPUM) and placed in the red zone for further treatment,” district police chief Wan Azlan Wan Mamat said in a statement.
A Taylor’s University student, speaking on condition of anonymity, said the relationship between the victim and suspect had soured dramatically after their break-up, with the suspect allegedly threatening his ex-girlfriend’s pet cat if she insisted on ending the relationship.
“He sprayed the cat with bug spray. I think it really died. There’s a video of the incident being shared among students,” the student told This Week in Asia. The victim was reportedly being detained against her will before the attack.
Police said the suspect was apprehended at the scene and that the motive was still under investigation.
