A group of teenage girls beat up a mentally disabled woman in Delaware County, Pa., videotaped the attack and posted the clip to Facebook, according to Chester police.
In the video, which was obtained and published by the Delco Times, a group of six girls approached the woman, who was sitting on her stoop.
One of the attackers started punching the 48-year-old woman. The attack then moved inside the home, where the teens continued punching her with their fists and hitting her with chairs, among other things.
