Women's Judo Medalist Punches Man Who Threw Bottle Before 100m Final

This was kind of weird and kind of scary. If you were only paying attention to Usain Bolt and the rest of the fastest men in the world just before the 100m finals started in London, you missed something. Someone threw a bottle out of the stands, and it landed just behind the blocks.
I say weird because ... who does this? And scary because that beer bottle could've been anything. That it came flying out of the stands and onto the track has to be a tad bit unnerving in a security sense.
Look closely at the following GIF. You can see the bottle land in lane five a couple yards behind the blocks.


Luckily it landed harmlessly. In fact, nobody -- save for perhaps the man in the orange bib -- seemed notice. But there it was, bounding towards the blocks just before the starting gun went off.
Edit: And this story gets better.

Dutch judo competitor Edith Bosch tweeted that she had punched the "drunken" culprit.
