What caused it -
"The incident happened at about 4:55 p.m. July 4 at the East Syracuse Walmart on Basile Row.
Officers were dispatched to the store for a report of fighting among five to six people and had been told “employees were being threatened, struck in the face and that customers had also been pepper sprayed,” Pace said.
Tyreana Edmonds, the woman who was hit, faces several charges stemming from the altercation with other people in the store, police said. She also has been charged with second-degree attempted assault of a police officer for trying to bite Spain, police said.
Another woman who Edmonds identified in the video as her sister, Tajenik Byrd, has also been charged. Pace said Byrd used pepper spray during the argument with other people in the store.
According to body-worn camera footage posted by the DeWitt Police Department, a man at the entrance of Walmart directed Spain to two women the man alleged were involved in the reported fight.
Store surveillance shows the earlier altercation that lasts about 30 seconds. In the video’s narration, Pace said Byrd pepper sprayed another woman. Byrd can be seen pointing something in her hand at another woman in the store. The woman then covers her face and moves her children away from the area.

Second-degree attempted assault of a police officer

Byrd was charged with:
