This is nothing out of the "ordinary" tbh. There's even a term for it. In Korea it's called sasaeng. Obsessive "fans" who stalk, threat, invade and harm others and their idols to be close to their faves.. furthermore its not like we sadly haven't heard of cases where fans came to an artists show only to murder them :(
I don't understand how someone can be this obsessed and hateful to someone that they haven't meet to the point of physically harming the other person. What kind of motivation did they have? I understand if they're taking revenge on someone who harm them and their family but those idols are just celebrity that has unclear hateful rumors. They don't even know you. Why going to such length tho? Is it their hormone? Or they're just lonely?
