Usain Bolt is still the fastest man in the world after he won gold in the Men's 100m.
He's the 2nd man to ever win the Gold in the 100m. Carl Lewis was the other.
Just after the announcer told the runners to set in the big 100m track and field finals featuring Usain Bolt some drunk guy launched a bottle on to the track.
If you Look you can see the bottle land in lane five.
Dutch judo bronze medallist Edith Bosch was sitting right by the guy and punched him in the face before police and security took him away.
None of the runners actually noticed the bottle. Usain Bolt laughed when reporters asked him about it.
A Scotland Yard spokesman said a man was arrested inside the Olympic Stadium on suspicion of causing a public nuisance and he remains in custody at an east London police station. No one was injured during the incident and that the event was not affected in any way
And, what a great moment here when Bolt was being interviewed, he actually stopped and watched the anthem being played when Sanya Richards-Ross was getting her gold medal.
