A woman has told police that a man flagged her down while she was driving and offered her gold in return for cash, claiming his credit card was not working.
The incident happened around 1pm on Monday, November 16, on the slip road connecting Tot Hill Services, near Highclere, with the southbound A34.
Hampshire Police say they have investigated previous scams where highly polished copper was made to look like gold and offered in return for cash so are appealing for help.
The man is of Middle Eastern origin, aged in his 30s and spoke German and English. He was 5ft 4ins, of a chubby build and wore a red chequered shirt and a brown jacket. His car was described as dark blue and there were three other men inside.
Anyone with information or who have been a victim of a similar scam should contact Hampshire Constabulary on 101 quoting 44150398276.
