Surveillance footage of Serena Williams chasing down a cell phone thief has been released.

Williams was eating dinner with a friend at a San Francisco restaurant Tuesday evening when she realized her cell phone was missing. Without hesitation, the tennis star jumped into action, weaving through the restaurant, chasing the thief down outside.

Williams posted about the story to her Facebook page Wednesday, saying it was her “SUPERHERO sense” that told her to keep an eye on the suspicious man by her table. She said when she caught up the the man, she sternly asked if he had “accidentally” taken the wrong phone. Caught by surprise, the man in question quickly returned the phone, saying, “It was so confusing in there. I must have grabbed the wrong phone.”

Good Morning America aired the restaurant’s surveillance footage Thursday morning, giving us the real superhero we all need in our lives.

In her Facebook post, she encourages others to “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!”
