Hate to bring this up, but...
There's nothing in this news report that suggests that the kid even started bleeding. Just that there was a "noticable injury" to his neck. That "injury", in the way it was phrased, could be a simple bruise, and in that case calling it a "minor incident" would be pretty accurate - kids attacking other kids is pretty mundane, and kids attacking other kids in such a way as to leave a bruise shouldn't happen, but when it does it is a pretty minor incident.
Now, note that I don't know anything more than what that article says. He could very well have been seriously injured, and in that case this would be a major incident.
In short: We don't know enough to judge whether or not this is "kid is almost killed" or just "kid is bullied a bit" (which would obviously also be bad, but nowhere near as much). And until we see other sources with more information, we won't.
