Protester lights arm and part of tennis court on fire during Laver Cup

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

The episode briefly delayed the action at the start of the second set of Stefanos Tsitsipas' 6-2, 6-1 victory for Team Europe over Diego Schwartzman of Team World at the O2 Arena.

The activist, carrying a lighter and wearing a white T-shirt with a message about private jets, made his way onto the black court and sat down near the net. The person eventually was carried away by security guards.
