There's A Video Of Serena Williams Chasing Down That Cellphone Thief

She wasn't kidding.

The other day, Serena Williams took to Facebook to tell a story about how she chased down a thief and intimidated him into giving her the phone back.

The tale was pretty epic, but it was always seemed to be lacking some form of video evidence.

Well, my friends, that video evidence is here, courtesy of ABC News. And here's Serena, in all her glory, running out of a crowded restaurant and hauling after the scumbag.
