Authorities say a girl is accused of attacking another girl, who appeared to be wearing a hijab, and now charges may be filed.

The alleged fight was caught on video, which has now been seen by thousands on social media.

It’s not totally clear what they were saying, but the student wearing purple can be heard saying, “You’re lucky you’re from another language, because I will crush you, [expletive].”

Several students KDKA spoke with call in incident unacceptable and say they are afraid of retaliation. They say the girl in purple has a reputation for causing trouble and they are hoping the district takes strong disciplinary action.
