London 2012 boss Sebastian Coe says it is was "poetic justice" that a man who allegedly threw a bottle at the 100m sprinters happened to be sitting next to a Dutch judo star at the Olympic Stadium.
A man was arrested by police after the incident just before the start of the men's 100m final.
Edith Bosch, the world judo champion who won bronze for The Netherlands in the -70kg judo, said she was sitting nearby the man had "beaten" the person who had thrown the bottle.
"I'm not suggesting vigilantism but it was actually poetic justice," Coe told reporters in London.
He added: "Throwing a bottle onto the field of play is unacceptable, it's not just unacceptable at an Olympic Games but at any sporting event and anybody who does that will be removed.
"There is zero tolerance for anything like that."
Bosch said on Twitter: "A drunken spectator threw a bottle onto the track! I HAVE BEATEN HIM .... unbelieveable."
