A protester lit his arm and an area of the court on fire during a match at the Laver Cup tennis event Friday, briefly delaying the start of the second set between Stefanos Tsitsipas and Diego Schwartzman at the O2 Arena in London.
The activist, who was wearing a white t-shirt with a message that said “End U.K. private jets,” made his way onto the court during a stoppage in play between the first and second sets. He sat down near the net and using a lighter, lit a small portion of the black court and his arm on fire.
