They reported the damage to the police and Cornwall Council as soon as they discovered it, which prompted a nine-year legal battle.
Sellers are prohibited from taking any items attached to the property, such as fixtures and fittings, without consent from the buyers.
Local authorities also have to allow permission for fixtures to be removed from a listed building.
Dr Payne was arrested on suspicion of theft, criminal damage and offences within the Planning Act at his new home in Cumbria by police, who recovered a small number of items in April 2015.
The council dropped the case over fears it wouldn’t be able to prove Dr Payne had caused the damage and he was released without charge.
Mr and Mrs Caton used historic photographs to show what the property looked like when they agreed to buy it and prove what had been taken.
They presented their case to the council again, who were advised by an external lawyer they hired that they had ‘ample evidence’ to prosecute.
But the council still refused to pursue Dr Payne – something which Mr Caton still cannot fathom.
He added: ‘It’s odd that if we were to change a small window without permission they will come after you, but if you destroy a house you are allowed to drive away with no consequences.’
In March this year, after fighting the case for nine years, the removed items were finally returned to the Catons after Dr Payne failed to supply evidence or appear at Truro Magistrates’ Court for a hearing under the Police Property Act to determine who owned them.
