[There was a video here]
NBC Philly reports the teens in the video were walking home when the unnamed 19th District officer confronted one of them. Neither the police department nor Damaris Abercrombie, who posted the video to Facebook, has commented on what led to the altercation.
The footage has been seen more than 100,000 times on Facebook alone. It's been shared nearly 5,000 times.
"The video does not reflect well on the officer," an anonymous police official told NBC, "I have no doubt he had good reason to be exasperated but you have to maintain your professional demeanor."
