Singapore Grand Prix winner Sebastian Vettel has called the man who walked onto the track during the Formula 1 race "crazy".
The safety car was called immediately when a person was spotted walking next to the barriers on the straight between Turns 13 and 14.
Vettel shouted on the radio when he saw the man, who climbed back over the barrier after the race was neutralised.
"I think I saw him take a picture," said Vettel. "I hope it was a good one at least, in focus.
"It was pretty crazy - we are approaching that corner at 280(km/h). I wouldn't cross the track if I was him.
"I don't know, maybe we need to block the grandstand a bit better. Fortunately nothing happened to me or to him.
"It was pretty odd, obviously that is not what you expect."
With nobody harmed, both Vettel and second place finisher Daniel Ricciardo were able to see the lighter side of the situation afterwards.
"He did a pretty good job - a quick runner," said the Ferrari driver.
Ricciardo, who felt both safety car periods in the race hurt his chances of fighting for victory, added: "Thanks to the guy on the track - appreciate it.
"I was tempted to swerve - clip him! Anyway, that was it."
