A newly-wed Australian couple are shocked and upset after their overseas honeymoon was ruined by a callous car-thief.

Dylan and Tayler Thomas were holidaying in the US when the couple's near-new Mazda was taken from their Adelaide home on Monday.

The car was then spotted on Tuesday night by police being filled up by a teenager at a Port Augusta petrol station.

Police launched a pursuit of the vehicle and after a long chase the car was abandoned, and police managed to arrest the suspect.

However the couple are devastated by the theft - and say they fear the culprit will return to their home.
