You wouldn't want to mess with Serena Williams on the tennis court. Now the number one tennis player in the world is showing that you don't want to mess with her on the street either.
Williams was dining at a Chinese restaurant in San Francisco when she says a suspicious looking man walked by her table.
Williams posted to Facebook about the incident, saying that she knew something wasn't right. The next thing she knows, her cell phone and the mystery man disappeared but Williams didn't waste a second catching the bandit.
Williams says she caught up with the guy and "politely" asked if he picked up the wrong phone.
The man says he was confused and made a mistake. When Williams got back to the table the crowd- watchers gave her a standing ovation.
Sounds like Williams is more than a super woman on the court...she's also a super sleuth!
