The sisters, who declined to provide their names, said the dispute stemmed from a pump malfunction that resulted in their gas spilling, according to Pittsburgh police. The women’s demand for a refund quickly escalated into a violent confrontation, which a bystander caught on video, police said.

The video shows the male store owners repeatedly striking one of the sisters in the back of the head and an employee grabbing the other sister by her hair and dragging her across the pavement. “It’s a lot more than just a simple assault,” said Sharon McIntosh, who is a member of the Greater Pittsburgh Coalition Against Violence.
