Scotland Yard has made six arrests in connection with a suspected fine wine investment scam.
Fraud squad officers believe that tens of thousands of pounds have been handed over by investors who were told they were buying premium Australian wines. Reports say the alleged offences had already netted the organisers more than £3 million.
Two women and four men were arrested at addresses in south east London.
Detective Chief Inspector Robin Cross of the Metropolitan Police's fraud squad said: "This kind of investment fraud is becoming far too common. People from all economic backgrounds are being targeted and persuaded to invest in what appears to be a sound financial opportunity.
"We would advise those considering investing money, whether it be a small or large amount, to do their research and be sure that the companies or individuals they are dealing with are reputable and legitimate."
