A man's been arrested after a bottle was thrown onto the track at the start of the men's 100m final at the Olympic Stadium last night.
A police spokesman said a man had been heard shouting abuse and was then seen throwing a bottle immediately before the race, won by Jamaican sprinter Usain Bolt.
Speaking after the race, US sprinter Justin Gatlin, who won bronze, said: "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."
