A conman is believed to have made more than £11,000 by offering cu-price champagne to office workers.
Detectives said that they were looking for a man with Brighton connections – John Clugston, 64, from Southwick – in connection with the scam.
They said that the “friendly” conman tells office workers that he is from a neighbouring company and has bottles of Bollinger left over from a party.
He offers to sell it for a good price, takes cash – up to £1,500 a pop – and fails to return.
The Metropolitan Police said that he had tricked people in the City of London and in Camden, Hackney, Hammersmith and Fulham, Kingston, Lambeth, Southwark and Westminster.
Det Cons Anna Petherbridge said: “He is friendly and engaging in his manner and gives his victims little cause for concern.
“However, he is slowly conning a lot of people out of a lot of money and we need the public’s help to track him down.
“We are keen to hear from anyone may know of his whereabouts.”
Anyone with information about the conman, who has the name Sharon tattooed on his right forearm, can call the Met’s non-emergency number 101 or the independent charity Crimestoppers anonymously on 0800 555111.
