The video, shot in May, shows a woman being attacked in broad daylight. The video shows the woman walking outside City Hall when a pack of teenage girls appears from behind her and slams her into the ground, hitting her repeatedly.

The woman said the attack was relentless.

"When I was in the air was when they got the first punch on my face that scared me I’ve never been punched like that,” she told myfoxphilly.com.
