Since the April 18 incident, a video of the attack has gone viral on the Internet. It shows the pair attacking a trangender woman apparently because she went to use the ladies room.
At one point, the two attackers grabbed the victim, Chrissy Lee Polis, by the hair and dragged her across the restaurant.
"They started ripping my hair, throwing me on the floor, kicking me in my face," Polis told the Baltimore Sun. "Everybody sat there in that McDonald's and watched me get hurt. And nobody did nothing at all. Nobody."
The video was shot by a McDonald's employee who can be heard laughing. Eventually, the video shows a customer who steps in and then an employee to stop the attack.
Polis, who is epileptic, appears to be having a seizure at one point. Workers point as she struggles on the floor, while another warns her attackers to run away. "Y'all need to get out of here, the police are coming!" an employee is heard on the video saying.
