One woman apparently used a stun gun on another after an all-out brawl inside of the Franklin Mills Mall in Northeast Philadelphia.The video shows the two women punching each other and someone in the crowd yelling, "No, stop."

After the two hit the ground, fighting, you can hear the crackle of what sounds like a stun gun and see fluorescent-colored sparks. Take a look at the video.
