According to the info I got, this happened in Malaysia. The video apparently recorded by a guy living in an apartment building across the street from where the alleged murder took place, shows the attacker chopping his victim with a bladed tool that looks like a meat cleaver.
The attacker gives zero fucks about the vehicles passing right by him, or the guy yelling at him while he’s filming the chop up.
Best Gore member @iwetimer provided some clarifying backinfo:
This happened near Penang Westland School in Penang, Malaysia. The teenager was attacked by his best friend. He survived, but remains in critical condition at Penang General Hospital.
