“Asian males”... Usually when I think of Asian, I think of Chinese, Japanese, or Korean.
Typically when thanks PC uses it they mean Pakistani, or even someone from the Middle East.
It’s usually British papers that refer to Middle Easterners as Asian. I assume the authorities here are referring to Asian in the same way you think of Asian.
It wasn’t jihadis or “Islamists” (whatever that means) or anything like that. Our Hero decided to play Batman and intervene in a domestic quarrel (girl hit boy with bag, boy hit girl with fist). Apparently his efforts at mediation were not appreciated and he got stabbed. Sometimes, MYOB is the best bet.
