MELBOURNE, Australia (AP) — A 16-year-old boy who was shot dead by police after stabbing a man in the Australian west coast city of Perth had been engaged in a deradicalization program since he detonated a homemade explosive device in a school toilet block two years ago, police said on Tuesday.

The boy had injured a man with a kitchen knife in a hardware store parking lot on Saturday night before police killed him with a single shot. The boy had told associates in a text message: “I am going on the path of jihad tonight for the sake of Allah.”

It was the third high-profile knife crime to shock Australia in recent weeks after two Assyrian Orthodox clerics were injured in a Sydney church and a Sydney shopping mall rampage in which six people were killed and another dozen were wounded.

Western Australia Police Commissioner Col Blanch said the boy killed in Perth had been a voluntary participant of the federally funded Countering Violent Extremism program since 2022 when he caused an explosion at a toilet at the Rossmoyne Senior High School, which he attended. The boy had received treatment for mental health issues as well as extremist inclinations.
