The funeral of 19-year-old Jojo Punvaree, a promising Muay Thai fighter fatally stabbed in Melbourne's CBD earlier this month, descended into pandemonium today when a group of approximately 10 machete-wielding youths arrived at the scene, according to eyewitness accounts. The incident, which unfolded outside the service, has sparked fresh outrage over youth violence and knife crime in the city, with some attendees describing it as a grim irony given Punvaree's death stemmed from a stabbing.
