Animated footage is being removed from the official website promoting the 2012 London Olympics amid claims it has triggered seizures.

The footage showed a diver plunging into a pool.

A London 2012 spokeswoman said: "We have just been notified of the problem and we have taken immediate steps to remove the animation from the website.

"We will now re-edit the film."

Graham Harding, an expert in epileptic photo sensitivity, told the BBC: "We now know of eight cases of which seizures have occurred.

"What it appears has happened is that the flash rate of the diving sequence contravenes the OFCOM guidelines."

The official 2012 logo

It has been reported that a number of sufferers had already contacted charity Epilepsy Action to say that they have been affected by the original pictures.

One caller told its programme how the video resulted in his girlfriend being treated in hospital after suffering from an epileptic fit.

The footage controversy follows widespread ridicule surrounding the 2012 logo.

The bold, jagged £400,000 brand, which is a modern take on the Olympic colours, took a year's research, including consumer testing.

Organisers have hailed it as dynamic and vibrant, but other people have said it resembles a "toileting monkey" or a "broken swastika".
