A fight ensued after a woman thought she had been cut in the checkout line at Walmart.
In the video, the woman rams another from behind with a shopping cart, then grabs the victim by the hair and slams her to the ground again and again.
A friend ultimately jumped in to help.
The attack happened in Greenville, Ohio, on Nov. 13. The woman attacked, Deanne Kenworthy, told Fox 45 that she was in line when she was asked to step aside to fill out some paperwork.
When she was waved back to a customer service representative to finish her transaction, Kenworthy told Fox 45 that was when she was hit with the shopping cart.
"I don't know this woman from Adam," Kenworthy told Fox 45 about her attacker. "I don't know where she came from I don't know where she lives."
Greenville police told Fox 45 that the suspect had caused trouble at the store two days before when she slammed a shopping cart into another customer she also claimed cut her in line.
Police are still looking to identify the suspect.
