The incident happened around 7 p.m. Monday at the Angorra Station when officers responded to a call for people on the tracks.

“An officer observed the pictured male leaving the track area and radioed to the sergeant who had just arrived at the station to stop him as he exited,” police tell CBS Philly.

That’s when police say the man “charged at her pushing her to the ground”.

The sergeant’s body cam shows her confronting the suspect.

The sergeant suffered a back injury in the attack.
