Protester Sets Arm On Fire In Wild Scene At Roger Federer’s Last Tournament

A man invaded the Laver Cup in London on Friday and set his arm on fire right next to the net — just hours before Roger Federer will play his last-ever competitive tennis match on the court.

The wild scene just went down minutes ago during a match at O2 Arena — when a guy wearing blue jeans and a T-shirt stormed the court with a lighter in his hand.

Video shot by witnesses in the stands shows the man sat down, made a fire — and then let the flames crawl up onto his arm.

Security raced in to smother the blaze — before they carried the guy off the court. No word if the man was seriously injured.

It’s unclear what message the guy was attempting to send with the protest — though his shirt did read, “End UK Private Jets.”

Despite the scene, Federer’s final match is still scheduled to go on later Friday — when he’s expected to team up with Rafael Nadal in a doubles event for the final match of his historic career.
