Banksy, the celebrated graffiti artist, is caught in the act for first time

His works command tens of thousands of pounds at auction and he counts Hollywood actors among his fans, yet his agent claims never to have met him.

Now it appears that Banksy, the elusive graffiti artist, has let his cover slip by being caught on camera at work for the first time.

He was pictured extending double yellow lines from a road on to the wall of an East London house to form a big yellow flower. To the left of the horticultural daubing sits a stencilled street-worker, sitting on a tin of paint and holding a roller. The picture was taken by a passer-by with a camera phone.
