Police have released a Google Street View image of a man which is believed to have been taken at around the time a caravan was stolen in Derbyshire.
The white Abbey Adventura caravan went missing from outside a house in Cauldwell Road, Linton, in summer 2009.
Its owner checked Google this year and spotted a man parked in the driveway.
It is thought the Street View car could have been passing shortly before the theft, and officers want to hear from anyone who recognises the man.
The theft took place sometime between 0930 BST and 1400 BST on 5 June.
Wheel clamps securing the caravan were removed and left behind, but despite forensic examination of the scene the stolen vehicle was never traced.
Pc Adrian Mason, who is investigating the theft, said: "It is amazing that we have such a clear image of a man who we think will be able to give us information that would help the police inquiry.
"It was an amazing coincidence that the Google Earth car was passing at that time.
"I've made extensive inquiries since the image was discovered but because the registration plate of the 4x4 is blanked out we have been unable to trace the man through his car. That is why we are appealing for the public's help."
Anyone with information should contact the Derbyshire force.
