Bosses at an epilepsy organisation are calling for Kanye West's latest music video to be taken off the internet over fears it could cause seizures among sufferers.
The hip-hop star's promo for All of the Lights, which features Rihanna, uses so much flashing imagery that regulators at the U.K.'s Ofcom authority have deemed the video unsuitable to be broadcasted on British television.
Experts at Cambridge Research Systems claim the video contains flashes that could trigger seizures in people with photosensitive epilepsy.
However, no broadcasting regulations regarding flashing imagery are in place online - so officials at Epilepsy Action are demanding that the clip be taken off YouTube.com, even though it has already racked up almost five million hits since its debut at the weekend (19-20Feb11).
