Dutch bronze medal-winning judo competitor Edith Bosch tweeted that she had punched a "drunken" man in the stands who threw a bottle onto the track just during the men's Olympic 100m final, won by Usain Bolt.
According to Australia's Fairfax press, British police arrested a man Monday after he allegedly threw the beer bottle onto the track just as the race was about to start.
The athletes were crouched, waiting for the start, when the bottle landed behind the blocks in lane five, a few metres behind Bolt's main rival and fellow Jamaican Yohan Blake, who claimed the silver medal.
London's Daily Telegraph reported that the bottle could be heard landing just after the starter told the runners to "set."
The New Zealand Herald reported that Bosch took to Twitter, writing in Dutch: "A drunken guest throws a bottle for me on the track! I have beaten him....unbelievable! #angry #disrespectful"
According to the Daily Telegraph, another spectator tweeted: "Man in front of me threw bottle onto track just at start! Had to be wrestled off ..."
Meanwhile, American bronze medallist Justin Gatlin told reporters: "It was a little distraction and I didn't know what it was.
"But when you're in those blocks and the whole stadium's quiet you can hear a pin drop.
"You just have to block it out and go out there and do what you got to do. You can't complain about that, the race went on and it was a great race."
GoJamaica.com also cited a police spokesman as telling reporters that the man was heard shouting abuse at Bolt as he prepared for the race.
However, accoridng to the NZ Herald, Bolt said he heard nothing out of the ordinary, and adding: "I don't know who would have done that."
Blake said he, too, was so focused he heard nothing: "I was so focused on just running to the line." The alleged bottle thrower was charged with causing a public nuisance.
