Thieves have made an audacious attempt to steal a Banksy artwork valued at 1 million ($1.97 million) by removing the bricks it was painted on from the inside of the building.
The Spybooth, which features three 1950s-style spies eavesdropping on a phone-box, appeared on the outer wall of an end-of-terrace house in Cheltenham, Gloucestershire, in April.
After several pieces of the wall were recently removed from the building without any sign of forced entry - the current owner of Spybooth, Hekmat Kaveh, is calling the attempted theft an inside job.
The local businessman agreed to buy the terraced house from the council for an undisclosed six-figure sum and has been looking to make a profit by selling it for 1 million.
He said: "It was a real surprise. When we realised the damage had been done we arranged to go in with the owner.
