A man tried to steal Serena Williams’s phone. It did not end well for him.

We're used to seeing Serena Williams perform superhuman feats on a tennis court. Watching her at her best is like watching a freight train take human form, an unstoppable force that swats away pretenders in less time than it takes most people to get ready for work in the morning.

On Tuesday, people got to see what happens when Serena Williams is pushed to be her superhero self in real life. According to Williams, someone tried to steal her cellphone and run away with it. It's unclear why an ordinary civilian would try to take something from a 21-time Grand Slam champion and think he could outrun her, but Williams recounted the experience on Facebook:

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

He began to run but I was too fast. (Those sprints came in handy) I was upon him in a flash!

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.

That Williams chased down a thief in the middle of a busy restaurant and this is the first we're hearing about it is a little bizarre. You'd think a tabloid would've gotten word of such an occurrence or that some picture on social media would've eventually turned up. But nevertheless, Williams said thwarting the would-be phone snatcher made her feel like a hero — a superhero:

"Always listen to your superhero inner voice. Always keep your things close! Fight for what's right. Stand for what you believe in! Be a superhero!" Williams wrote. "When I got back into the restaurant I received a standing ovation. I was proud. I just showed every man in there I can stand up to bully's [sic] and other men. It was a win for the ladies!"

If there's any lesson to take from this, it's that you don't mess with Serena Williams, on or off the court.

Update: There is now surveillance video of the incident.

Will you support Vox’s explanatory journalism?

Most news outlets make their money through advertising or subscriptions. But when it comes to what we’re trying to do at Vox, there are a couple of big issues with relying on ads and subscriptions to keep the lights on:

First, advertising dollars go up and down with the economy. We often only know a few months out what our advertising revenue will be, which makes it hard to plan ahead.

Second, we’re not in the subscriptions business. Vox is here to help everyone understand the complex issues shaping the world — not just the people who can afford to pay for a subscription. We believe that’s an important part of building a more equal society. And we can’t do that if we have a paywall.

So even though advertising is still our biggest source of revenue, we also seek grants and reader support. (And no matter how our work is funded, we have strict guidelines on editorial independence.)

If you also believe that everyone deserves access to trusted high-quality information, will you make a gift to Vox today? Any amount helps.
