Protestor sets arm on fire before Roger Federer retirement match at Laver Cup

During a match between Stefanos Tsitsipas and Diego Schwartzman, a climate change activist took to the court for the event inside London, England’s O2 Arena to make a very painful statement on their reported dissatisfaction with the United Kingdom’s use of private jets. The incident did not last very long and the protestor rubbed the fire off his arm soon after setting it ablaze. You can watch footage of the alarming moment above.

Following the protest, the Daily Mail reported that the man involved in the wild incident is a 20-year-old activist named Kai that had recently made several social media posts bashing the UK government for allowing the use of private jets. He is allegedly a member of the anti-private airplane group known as End UK Private Jets.

This is just the latest protest at a major sporting event over the last six months. This year’s NBA playoffs were hit with several on-court protests, including one woman attempting to glue her hands to the court. And in June, a woman attached herself to the playing net at the French Open to also protest the issue of climate change.
