In London held the world championship in athletics. On the eve of an unusual event.
Before the final race at the distance of 100 m on the treadmill ran a naked man.
The stewards pretty quickly twisted troublemaker and expelled it outside the competition area.
Recall that the final was the last race at the distance of 100 meters, the legendary Jamaican Sprinter Usain Bolt.
He won the bronze medal, behind Americans Justin Gatlin and a Christian Coleman.
Video of the incident can be viewed on YouTube.
