``You see them come charging on like the Light Brigade, you don't know what's going to go on,'' Waugh said following Wednesday's one-day match. ``It just takes one guy who has had too much to drink or whatever to do something silly.''

Waugh was overrun when about 1,000 spectators stormed the pitch during the final ball of the tension-filled fifth one-day international against the West Indies in Georgetown, Guyana.

One fan crashed into him, giving him whiplash, another grabbed his bat and others hurled taunts and threats as the Australians walked to a conference with officials.

``It doesn't get much scarier than that on a sporting field,'' Waugh said.The invasion came as the West Indies appeared set to win by one run. But it caused International CricketCouncil referee Raman Subba Row to declare a tie. He also ordered an investigation into the incident.

``There have been a couple of other incidents like this, but at all times, the safety of the players and officials is the absolute priority,'' ICC Chief Executive David Richards said on Thursday in London.

Richards said he didn't see the match, but ``a tie sounds like a reasonable outcome. We're happy to leave it in the hands of the match referee,'' he said. Cricket fans in the West Indies have traditionally been a different breed than those in the game's birthplace, England, where it is considered a gentleman's sport.

In the Caribbean, loud, enthusiastic crowds give matches the raucous excitement of a soccer spectacle.

``But this time, the enthusiasm went too far,'' Waugh said.

Six years ago, on the same Bourda cricket ground, Subba Row declared a draw in similar circumstances when the West Indies seemed to have beaten Pakistan.

Then, ian Bishop completed the winning second run off the last ball,but Subba Row ruled that the Pakistanis had been impeded by the marauding spectators.

Tim May, president of the Australian Cricketers Association, said on Thursday that the Bourda ground needs better security. A former Australian captain, Mark Taylor, suggested fences with barbed wire on top might be needed to keep fans back.

``The ground has a history of past trouble, and obviously they have to bring in measures to stop it happening again,'' Waugh said. ``I don't think we should accept it any more. There will be someone seriously injured. It's unacceptable.''

The seven-match series, which remained tied 2-2, concludes with two matches in Bridgetown, Barbados, on Saturday and Sunday.
