Passing a two-year sentence at the Old Bailey, Judge Philip Katz told him he could see no other reason for him doing it “other than greed”. “There was a gravy train passing by and you wanted to jump on it,” the judge said. “This is, in many ways, a tragic case because, as you realise, the scale of this fraud and the fact that you have denied it in the face of overwhelming evidence means there is only one way I can deal with you – it is to sentence a hard-working doctor to prison. He added: “You got greedy. You were living an ordinary and respectable life, you come from a respectable background of professional people who, I expect, are horrified to witness what happened as a result of the choices you have now made.” Chang, who was born in Hong Kong, sparked anger among animal-lovers in 2009 after he was photographed sitting on the head of an elephant he had shot in Zimbabwe. He defended killing the beasts, insisting it helped local people, and survived the public backlash to keep his job. But the latest scandal is almost certain to end his medical career for good and he has recently been scraping a living with driving jobs and by working in a restaurant. The court heard Chang systematically defrauded insurance companies by billing them for physiotherapy sessions which never took place. The scam lasted for two years until one of the insurance companies became suspicious about the number of invoices coming from Proteus Healthcare. A big game-hunting Harley Street doctor who faked invoices worth almost £200,000 for non-existent treatment has been jailed for two years. Dr Benjamin Chang, 57, was at the heart of a controversy after he was photographed giving the thumbs up next to a dead elephant during a hunting trip in Africa in 2009. His career is now in ruins after he was found guilty of a two-year scam against insurance companies by billing them for non-existent physiotherapy sessions. Chang claimed £183,000 while running his private medical practice from Milton Keynes, but also used consulting rooms at Harley Street.

Their investigations revealed Proteus was being run by Dr Chang and the physiotherapist supposedly providing the treatment did not even exist. Prosecutor David Povall said Chang was carrying out the scam “to enrich himself” and pay off his debts to his family. Mr Povall said: “The police found dozens of examples of cases in which Benjamin Chang had supported claims from Proteus Healthcare for physiotherapy. “They seized Dr Chang’s computer server and found dozens and dozens of Proteus invoices for named claimants purportedly signed by Helen Preston. “What the Crown is suggesting is that Proteus Healthcare is not a business that provides physiotherapy – it is a business that provides invoices for physiotherapy. “Dr Chang knew that these invoices were false, that there was no physiotherapy or not the amount being claimed for.” Chang, of Mill Hill, north London, denied fraud by false representation.
