An investigation is underway after a flash mob was caught on video attacking and robbing four underage teenagers in Center City.
One of the victims, a 17-year-old girl who did not want to be identified, told NBC10 she and three of her friends - another girl and two boys - were getting food at the Wendy's restaurant on 15th and Chestnut streets Monday around 6:30 p.m. when they were suddenly attacked by a group of at least 20 teens.
"I remember them saying, 'Get her.' And then the next thing I know, my face was burning and bubbling," the girl said.
The teen told NBC10 the group beat her, used pepper spray on her and stole her phone, wallet and ear buds.
