On Tuesday, the police arrested a 14-year-old boy at a school in Petaling Jaya in connection with Yap’s fatal stabbing. 

The incident occurred at SMK Bandar Utama Damansara (4), Petaling Jaya, which is located a short distance away from the popular 1 Utama Shopping Centre.

Malaysian authorities said that the suspect had allegedly stabbed Yap outside a classroom and she died at the scene.

Selangor police chief Shazeli Kahar on Wednesday confirmed that she died from multiple stabs to the chest and neck, local media Malay Mail reported. 

“The victim was found in the toilet and based on our current investigation, we believe the suspect had followed her inside,” Shazeli said. 

He added that the suspect, a Form 1 student, is believed to have an infatuation with the victim and was a “secret admirer”. Yap was a Form 3 student. 

“Our investigation so far has found that the suspect had feelings for the victim but did not share them, it was more of a case of harbouring those feelings. It is also believed that the victim was unaware of the suspect’s feelings,” he said at a press conference on Wednesday, as quoted by Bernama. 

According to Shazeli, the suspect and the victim had no prior relationship or interaction, noting that “emotional factors and social media influence” are believed to have contributed to his actions. 

Shazeli also confirmed that the authorities had seized a written note from the suspect. 

The note had read: “This world is fake. I have won.”
