A 34-year-old man has been charged with a public order offence after a bottle was thrown at the start of the men's Olympic 100m final on Sunday night.
Scotland Yard said Ashley Gill-Webb, of South Milford, North Yorkshire, was due to appear at Stratford Magistrates' Court later.
After the incident a Dutch judo champion hit a man she had seen throwing a bottle on to the track.
Edith Bosch, 32, said she hit him on the back with the flat of her hand.
A Locog spokesman said: "The incident had no impact on the competitors or the event."
However, US sprinter Justin Gatlin, who won bronze in Sunday's race, said the bottle had been a "little distraction".
He added: "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."
A police spokesman said Mr Gill-Webb had been charged with intentionally causing harassment, alarm or distress under section 5 of the Public Order Act.
John, who was sitting three feet away from the man, told BBC Radio 5 live: "Police dragged him down the tunnel where the athletes come out.
"The biggest cheer went out for this guy getting arrested as actually Usain Bolt getting over the line," he added.
Ms Bosch, who won a Bronze medal in the 70kg category, said the incident made her miss the race.
"I am very sad about that," she added.
London 2012 chairman Lord Coe said: "Throwing a bottle onto the field of play is unacceptable. It's not just unacceptable at an Olympic Games, it's unacceptable at any sports venue.
"The guy was removed and anyone who does that in future will be removed so there is a zero tolerance to anything like that."
He added that it was "poetic justice" that the man had been sitting next to a judo athlete.
