An unknown man assaulted actor Arnold Schwarzenegger during a public appearance in South Africa on Saturday, but the 71-year-old appeared to quickly recover and say "I'm just glad the idiot didn't interrupt my Snapchat."

Video shows the former California governor standing and filming children at a sporting event in Johannesburg when a man makes a flying kick into his back. Schwarzenegger stumbles forward. The man is quickly grabbed by security. Off camera a man shouts several times "Help me!"

The video shortly afterward shows Schwarzenegger smiling and shaking hands with bystanders but then walking out ringed by security.

Schwarzenegger later posted on Twitter: "Thanks for your concerns, but there is nothing to worry about. I thought I was just jostled by the crowd, which happens a lot. I only realized I was kicked when I saw the video like all of you. I'm just glad the idiot didn't interrupt my Snapchat."

He had been attending his Arnold Classic Africa event, which features dozens of sports and fitness activities. In a separate Twitter post, the event blamed a "crazed fan" for the assault.

The statement cited organizer Wayne Price as saying the assailant was "known to the police for orchestrating similar incidents in the past" and that Schwarzenegger was "fine and still in good spirits."

The actor confirmed he had no intention of laying charges and would continue with another appearance on Sunday as planned, the statement said.
