Philadelphia Police have identified seven of the eight young people who they say were caught on camera attacking a woman and stomping her unconscious along a Center City sidewalk last month.
The Philadelphia District Attorney's Office approved charges for the seven suspects, who they described as "juveniles" and police are working to take them into custody, officials announced Thursday night. Police confirmed with NBC10 that three of the suspects turned themselves Thursday night. A law enforcement source on Friday said seven people had surrendered.
Six of the suspects have been arrested and charged with aggravated assault, robbery, criminal conspiracy and related offenses, police said.
Those suspects are between the ages of 11 and 14.

On Tuesday, police released surveillance images and video of the Feb. 23 attack at 15th and Chestnut Street that left the 34-year-old victim with injuries to her head, face and body.
The attack happened at 7:12 p.m., police said.
"Several people in a group assaulted her knocking her to the ground," police said. "The suspects then continued to punch and stomp the victim rendering her unconscious."
The woman, who suffered several injuries, including a fractured face, was treated at a nearby emergency room, investigators said. She told NBC10 she's been afraid to walk far from her apartment since the attack and wants to move out of Philadelphia.
Police released photos of eight people wanted in connection to the beating. Following the attack, some members of the group can be seen walking away, while at least one of them hops on a bike, video shows. Photos show at least three of the suspects used bicycles.
