There was a conflict between two of my friends at school

One of them literally bit, punched, beat among other things with the other

I just came to the other one just to ask them what happened and she told me to tell it all to one of the school staff

I came to one of the school staff and told it to her

She sended me and the victim to the psychology room (yeah ofc there's a psychology room in the school)

A few moments before the agressor came here, the victim told that the agressor had a series of agressions toward the colleagues at school

And some moment later, the same agressor entered there

And she told us everything when the school coordinator (the same person who sended me and the victim to the psychology room) asked her to tell why did she start the conflict

She told that it was a very long story

The story starts with her and someone she was friends since 6 years in a friend group (in which i believe it was a group chat created by a friend of hers), some time later, the victim was added to the group

There were several drama incidents between these people, and that caused her to have a anger crisis (in which she told she was having that since she was 9 years old)

As a person who's friends of both these people, i never expected something like that to happen. Not even at school

And despite all of this, it's also said that the agressor literally said in a leaked message (by idk who) that she is going to attack the victim tomorrow (in which i believe that message was sent yesterday because that attack happened today)
