Police have arrested a girl shown beating another girl and her brother in a terrible fight video that has gone viral.

The original clip went viral after it was posted online—showing a young girl attacking another girl who seemed to be confused as to why she was being attacked. The most disturbing part of the video by far was when the victim's little brother tried to protect his sister, the assailant punched him as well.

Police believe the girls knew each other from high school, but aren't releasing names because everyone involved is underage.

Rev. Charles Harrison told WXIN these videos are a new form of "street cred" amongst young kids.

This is glamorized, this is glorified, this brings them ‘street cred,’ this brings them notoriety, ya know? She’s tough, she’s going to beat somebody up. It’s almost like they plan these fights, they want these fights to be on tape where they can put it on social media. This is horrible.

The original video, seen below, is disturbing.
