A boys' club who had a rare piece of Banksy artwork left on their front door have had it valued on the Antiques Roadshow for £400,000.

The work, called Mobile Lovers had appeared overnight on a plank of wood screwed to a wall close to the Broad Plain Boys' Club in Banksy's home town of Bristol.

Dennis Stinchcombe from the club, became involved in a row with the local council after removing the artwork put on a public wall near the youth club.
