Violence broke as fans made their way from Upton park tube station along Green Street to the stadium. Posted by "irock920".

West Ham equalised at 86 minutes, resulting in the first pitch invasion. They then went on to score two more goals at extra time at 97 minutes and 99 minutes. Video posted by "Jahan26".

Steve (not his real name) is a former "West Ham Boy" from the East End. He remains a devoted fan but says he no longer takes part in the violence. 

As soon as the fixture was announced, they knew they'd got the opportunity to have a rumble. The old school West Ham boys - 40, 50 years old now - phoned up their old contacts and arranged where to meet. ‘All right there captain, we're coming over for a rumble. I'll meet you and so-and-so...near this pub...after the match...at this time'. You know what I mean? Just like 20 years ago. We've all known each other from the eighties.

There was no way it could ever have been stopped; it was planned the minute the game was announced. A lot of guys don't even go for the match, you know what I mean, they just go for the fight. It was carnage. It was all the old school boys plus all the wannabes.

Worst of all it was a night match, so it's difficult to know what's going on when it's pitch black everywhere. They failed to police it properly, they weren't expecting as much trouble - these things don't happen much in football any more. The police shouldn't have let it happen."

The history of the rivalry between the two teams is to do with the old dockers... Millwall is just south of the river [originally north] and West Ham is just north... it's basically going back to the 1920s when they broke strikes. They really loathe each other, there have been murders and all sorts since then. In a very strange way, it's tribal.

They [Millwall FC and West Ham FC] haven't met for four years, and the last time there were 1,800 police officers. Plus it was a Sunday morning match, which is much easier to police. With a morning match there are only one or two trains they can take to get to the game, so the police know they're going to be on one of those two trains. They're going to know exactly who the gang of blokes on a train at half past nine in the morning is.

But if it's an evening match, well... They've been doing this for dozens and dozens of years now, so they know exactly what they're doing. Sixty blokes will go across at nine o'clock in the morning and sit in some cafe, in a pub for the day. Another 60 blokes will go at lunchtime; another 60 will go in the afternoon... so the police can't control it.

It is actually the police and the FA's fault for putting the match on in the evening. Someone made a decision and it was the wrong one. Millwall and West Ham fans must have been rubbing their hands together in glee when they announced it!"
