An American pensioner with dementia was flown to Britain and left in a car park by his wife and son, according to court documents in the US.

Roger Curry was allegedly abandoned in the car park of Hereford bus station on November 7 2015 after travelling from his home in Los Angeles with his wife and son.

Legal documents seen by the BBC's Panorama programme and filed in Los Angeles state: "In late 2015 Mr Curry was taken surreptitiously to England by his wife Mary Curry and his son Kevin Curry and abandoned there."

The 76-year-old, who did not know his name or where he was, was found in the company of two men who flagged down a passing ambulance.

One of the men - described as having an American accent, but younger than Mr Curry - allegedly vanished from the scene.

Mr Curry was taken into the care of a nursing home while police and social services spent months trying to find out who he was.

He was finally flown back to America eight months later and is now under the care of authorities in Los Angeles.

At the time of his discovery, police appealed for help to identify the "vulnerable" man.

West Mercia Police said they also wanted to trace a man, described as being in his forties, who was seen to be walking with Mr Curry towards Hereford County Hospital on the day he was discovered.
