A suspected fraudster dressed as a smart businessman and stole diamonds worth �32,000 in a “sophisticated scam”, transport police say.

On October 28 at St Pancras International Railway Station, the man received two expensive diamonds from a dealer who was allegedly fooled into thinking there had been payment.

Brtish Transport Police have released CCTV images of the suspect who called himself Michael Levy, wore a pin-stripe suit and claimed to be based in Hatton Garden.

The dealer travelled from Antwerp, Belgium, for the exchange at St Pancras after his bank informed him Levy had paid for two specific diamonds.

However when Belgium colleagues realised there was no payment Levy had already left the station with the valuable jewels.

British Transport Police Detective Constable Eloise Lock said: “This was a sophisticated scam that involved faking a telephone call from a trusted source at the bank.

“By the time the trader realised the phone call had been faked the deal had already been made.

“An address in Hatton Garden provided by the buyer was then found not to exist.

“I am appealing for anyone who recognises the man in the images to get in contact as we believe he can help us with our enquiries.”

The stones taken were an H coloured VVS2 purity 2.01 carat diamond an H coloured VS1 purity 2.01 carat diamond. Transport police say the buyer mentioned he had a brother called Samuel Levy.

Anyone with any information about this incident, or who recognises the man in the images, is asked to call British Transport Police (BTP) on 0800 40 50 40 quoting incident number B2/LNA of 17/11/2011. Alternatively, call Crimestoppers on 0800 555 111.
