Opening the case at Stratford Magistrates' Court in east London today, prosecutor Neil King told the court the Games had reached a highlight with the men's 100m final:
In the stadium, along with the many thousands who should have been there legitimately and were watching the race in hushed anticipation, was also Mr Gill-Webb who it is now accepted was unwell at the time.
His conduct at the time however, the Crown say, was one that was causing harassment, alarm and distress to those around him and his conduct was one that he intended to case harassment, alarm and distress.
He had somehow, without a ticket ever being found on him, made his way into very exclusive seats indeed.
He was mingling with members of the Dutch Olympic team. Indeed he would be within striking distance of a bronze medallist Ms Edith Bosch.
Whilst there he hurled abuse towards the athletes in the final, particularly towards the eventual winner Usain Bolt.
