LONDON (AP) — London police say they have arrested a man for throwing a bottle on to the Olympic track at the start of the men's 100-meter final.

Scotland Yard says a man was heard shouting abuse and was then seen throwing a bottle immediately before the race.

Jamaican sprinter Usain Bolt, who won the race, told reporters he had been unaware of the incident. He said Sunday: "No, I keep hearing that. I don't know who would have done that."

Police said no one was injured and the event was not disrupted.

The suspect is being held at a police station in east London on suspicion of causing a public nuisance.
