The video, taken by a fellow high schooler, quickly went viral after he posted it on Facebook.
“I don’t know why she hit the cop,” the teenager told INSIDE EDITION, which is not using his name because he says he has received online threats.
He has known the girl in the video since they both were in the sixth grade, he said. “As far as I know, she has been an honor student since middle school,” he said.
“I didn’t know she was capable of this and I do not know why she did this,” he said.

Phone messages left by INSIDE EDITION with the Allentown Police Department were not immediately returned.
The four injured cops have all been treated and released from a local hospital, authorities said.
