A Protester set his arm on fire at Laver Cup.

A protester lit a portion of the court and his arm on fire during a match at the Laver Cup tennis event at London's O2 Arena, hours before Roger Federer was scheduled to play for the final time before retiring.

The man, protesting about the use of private jets in Britain, sat down and lit a substance on his arm during the match between Stefanos Tsitsipas and Diego Schwartzman.

Laver Cup organizers confirmed that the protester has been arrested and the situation is being handled by the police.
