Dutch medal-winning judoka Edith Bosch has described trying to restrain a man who threw a bottle at the start of the Olympic men's 100m final.
"He was standing in front of me, and I pushed him and said 'Guy, what are you doing'," said Bosch, speaking to reporters outside the Athletes' Village.
The 32-year-old had got her hands on a ticket to London 2012's most anticipated event, but ended up missing the race - won by Usain Bolt in the second fastest time in history - because she was dealing with the unruly fan.
"I couldn't believe that somebody could do such a thing. After that I realised that I didn't see Bolt win, and all the other guys who were running. I was like, because it was nine point seconds and there was commotion, 'It's over'. So that's it."
The spectator, who has been charged on suspicion of causing a public nuisance, was removed from the stadium and taken to a police station in east London. He denies the charges.
