Serena Williams chases man after phone 'grabbed' in restaurant

Here's a tip for anyone planning to grab Serena Williams's phone - don't bother.

The American, who has won 21 Grand Slam singles titles, will chase you down, and she will catch you.

Fit, strong and apparently rather fast, you don't want to mess with tennis star Serena Williams

It was a lesson learnt by a man who took the 34-year-old's mobile phone while she was in a restaurant.

The world number one put up on her Facebook page a picture of herself as Superwoman and the following post,

“Yesterday at dinner the craziest thing happened to me.”

Williams, who is taking the rest of the year off to recover from injuries, claimed the man "grabbed her phone and swiftly left". She posted,

"Not thinking I reacted (hence the superwoman photo), I jumped up, weaved my way in and out of the cosy restaurant (leaping over a chair or two) and chased him down."

Williams said that she was "too fast" for the man and was "upon him in a flash".

She added,

"In the most menacing, yet calm, no-nonsense voice I could muster, I kindly asked him if he 'accidentally' took the wrong phone. He stumbled on his words, probably not expecting this to happen. Eventually he said: 'Gosh, you know what, I did! It was so confusing in there. I must have grabbed the wrong phone.'"

Williams, who won every Grand Slam singles title except the US Open this year, said she received a "standing ovation" from her fellow diners at the restaurant.

She described it as a "win for the ladies" and said she showed "every man in there I can stand up to bullies".
