The legendary artist known as Banksy is believed to have been caught on video just hours after his latest graffiti creation appeared on the side of a bridge.

Footage has emerged of what looks to be the elusive artist acting shifty while sporting a baseball cap and sunglasses to shield his identity.

Banksy took responsibility for a piece of art slapped to the side of the disused Scott Street Bridge in Hull, East Yorks., on Friday (Jan 26).
