I thought that's what you were referring to.
Keane did not headbutt a woman, you've fabricated that. Not even the woman herself alleged that, merely that he kicked her in the thigh, which was also untrue.
You are aware aren't you, that the woman in question, Maxine Rourke, was, along with her husband, reported to be financially bankrupt in the Manchester Evening News just 2 months beforehand. She sold her story to The Sun for a large sum of money. A spokesman for the bar said that:
The allegations from the two women, was that Keane kicked one of them in the thigh, and poured a drink over the other, not that he headbutted one. Neither allegation was substantiated by any eyewitnesses, who said that the ladies were rude, abrasive and clearly looking for trouble, and that Keane did not attack them in any way, shape or form. The police agreed, and hence he was not charged.
The Sun's picture along with the article was taken before the incident happened, which strongly suggests it was a set-up. The ladies were staying in a hotel nearby, which it also appears was paid for by The Sun. They rang The Sun afterwards before ringing the police.
The Sun got their big story before the FA Cup final, the ladies got their payout. All of it was total bollocks of course. I'm not surprised that not only you bought it hook, line and sinker but that you altered the already untrue 'kicked in the thigh' to 'headbutted'.
