I’ve tried to understand what the charges are, as far as I could tell it seems it’s somehow related to an anti terrorist law and caused by the kid pulling someone’s hair and gesturing to cut paper with scissors, which was interpreted as gesturing to cut a finger.
The article seems to try very hard to obfuscate the actual reason (I’m guessing for legal reasons?)
In any case, this seems insane, seems like excessive overreaction from everyone involved.
