West Ham owner David Sullivan has warned there will be riots in east London if rivals Tottenham move to the Olympic Park stadium after the Games.
Sullivan fears 'civil unrest' due to massive opposition from football fans in the West Ham heartland to Tottenham's proposed relocation.
He said: 'It would be such a slap in the face to east London. If it happens, there will be real problems that could easily lead to civil unrest.
'I think there could be riots, such is the ill feeling between West Ham and Spurs and I know the police feel the same.'
A Tottenham relocation emerged on Tuesday as a strong possibility, with sports and entertainment company AEG, who are partnering Tottenham in their official proposal to the 2012 legacy company, putting their considerable weight behind it.
As well as alienating West Ham, who had talks with AEG before they linked up with Spurs, the plan not to include a running track in the football conversion will infuriate London 2012, who have made repeated pledges that track and field will be a permanent legacy from the Games.
Spurs fans, who have not been consulted on moving from Tottenham High Road, will be exercised further by the transfer to Stratford looking increasingly like the preferred option rather than merely a back-up to the Northumberland Development Project at White Hart Lane.
Sullivan said: 'I feel very let down by Tottenham. The way they do business is not right. They pinched Eidur Gudjohnsen off us after we brought him from Barcelona for talks. He just disappeared from the hotel. And the way they unsettled Scott Parker was appalling.
'Now they want to move into our borough of Newham. How would they like it if we suddenly set up a new home in Haringey. I'm flabbergasted by the cheek of it.'
Both Tottenham and AEG insist that a football stadium doesn't work with a running track.
AEG president Tim Leiweke said: 'We want the venue to be perfect for football for the next 30 years, rather than the odd athletics meeting. Tottenham are a good fit whose supporters can fill a 60,000 stadium, while it would be a bit of a miracle if West Ham are in the top five of the Premier League.'
Leiweke was given the opportunity to make his pitch with Tottenham by the Olympic Park Legacy Company not insisting on a running track being part of the tender process.
And his comment: 'We are selective with our projects and successful' is confirmation that this is no Plan B for Tottenham.
