A New York City fast food worker is unable to work after a mob of teen girls viciously attacked her following an argument at a Wendy’s restaurant. The video shows the girls beating the employee while yelling and screaming:

From WNYW:

A Wendy’s employee told Fox 5 that it started with one girl attacking the woman and a large group of them jumped in and punched her. The worker said it all began when the group started fighting and throwing food. She was behind the counter when her co-worker walked over to try and stop them, she said.

The woman who was attacked suffered a concussion and is currently unable to work.

Police have identified two of the girls and are working with a nearby school to identify the rest. The Wendy’s franchise director, Louis Meyer, released a statement to WNYW that read in part:

This vicious attack on our female employee was shocking and uncalled for. We are cooperating with the police in their investigation and our security camera data and anything else they request will be provided to them.
