Sebastian Coe said it was "poetic justice" that the man who threw a bottle at the 100m sprinters last night happened to be sitting next to a Dutch judo star.
Edith Bosch, the Netherlands’ world judo champion who won bronze in the -70kg judo, said she had "beaten" the person who had thrown the bottle.
The man was subsequently arrested by police. The incident took place just moments before the start of the 100m final.
Coe said today: "I'm not suggesting vigilantism but it was actually poetic justice but they happened to be sitting next to a judo player.
"I think the expression is ippon."
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."
London 2012 organisers said that the person who threw the bottle had bought a ticket for the event.
