Christal Spann is the woman who claims she took a picture of Chris Brown, who then stole her phone (a $500 iPhone 4S) and yelled, "Bitch, you not gonna put this up on a website." And in this video taken moments after the incident, Spann and her two friends seem sincere as they tell the police what happened, and there's no apparent discrepancies between what they say here and what they would say later in the police report.
Brown hasn't said anything about this on his twitter, and no warrant has been issued yet, but if it is, and he's found guilty, that would violate his probation. But first they have to prove that someone with such a well documented respect for women would steal a girls phone and call her a bitch. Good luck with that.
