Mayor Michael Nutter said Thursday he has seen the video about 20 times and is “sickened” and “ashamed” by what happened.
A 36-second video posted online shows Aida Guzman being struck in the face and falling to the ground, her face bloodied, and then being led away in handcuffs. Police say people had been throwing liquid at officers during a celebration at the city’s Puerto Rican Day parade.
Prosecutors have withdrawn a disorderly conduct charge against Guzman.
The Philadelphia Fraternal Order of Police has said Josey is eager to speak to internal investigators.
