Fan hops security wall and tries to attack Dean Ambrose

A video has surfaced online showing a WWE fan hopping the security wall trying to attack Dean Ambrose as he was making his way to the back during
the Smackdown tapings. A WWE security guard who was standing next to Ambrose as he was greeting fans in the aisle noticed the fan just in the nick of time and tackled him to the ground. After assessing the situation or a second, a cool Ambrose then turned his back again and raised his hands and continued to high-five fans. You can see the video here
