A protester sets fire to a hand and part of a tennis court during the Laver Cup

A protester set fire to part of the court and his hand during a match at the Laver Cup tennis tournament on Friday, an hour before Roger Federer was due to play for the last time before his retirement.

The episode briefly delayed the action early in the second set as Stefanos Tsitsipas cruised to a 6-2, 6-1 victory over Team Europe’s 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, headed to the black court and sat near the net. Eventually, the security guards took the person away.

“It came out of nowhere… I’ve never had an incident like this on the court,” Tsitsipas, the 2021 French Open runner-up, said afterwards. “I hope he’s okay.”

Tsitsipas spoke to the chair umpire to make sure it was safe to continue the game and asked to clean up the mark left on the pitch.

The protester “has been arrested and the police are dealing with the situation,” Laver Cup organizers said in a statement.
