It appears that right before the 100 Meters final a fan threw a beer bottle at Usain Bolt.
The attempt though failed miserably and as you already know didn’t effect Bolt smoking the field to win the Gold in 100 Meters.
The funnier thing is what allegedly happened to the fan who threw the bottle.
Edith Bosch, a female Dutch judoka who won a bronze medal earlier during the Olympics, claimed that the man who threw the bottle was sitting near her and that she “beat” him. Whether that’s true or the hyperbole of an aggravated athlete was unclear in the minutes after the incident. Pictures show a contingent of Dutch athletes sitting behind the starting area. The thrower was reportedly arrested and taken into custody.
