The bizarre protest at the O2 Arena in London came as Roger Federer prepared to play the final match of his career and with the 41-year-old sat courtside.
The protester made it past security to get onto the court before staging the protest, setting his right arm on fire.
The incident was not shown by broadcasters, but pictures from courtside showed the man was screaming in agony.
He was then removed from the court by security and was led away from the arena.
The man wore a t-shirt which read: “End UK private jets”.
The match resumed after the man was detained and there was a further delay as liquid was cleared from the court.
Earlier this year, a semi-final match at the French Open was interrupted by a protester who chained herself to a net.
