The French surgeon accused of carrying out a botched operation on the French rock legend Johnny Hallyday has been attacked by two hooded men in Paris.Doctor Stephane Delajoux operated on the man known as the “French Elvis” after he suffered a slipped disc last month. Hallyday has since had to undergo emergency treatment in Los Angeles. The singer’s fame is such that even French president Nicolas Sarkozy has conveyed his best wishes. Other stars, including Charles Aznavour have been at the 66-year-old’s bedside. Hallyday remains in a medically induced coma after suffering an infection following the initial operation in Paris. The media frenzy surrounding Hallyday’s illness went into overdrive when the French rocker’s producer compared Hallyday’s Paris operation to “butchery”. Delajoux’s lawyer insists there was “absolutely no negligence” involved. According to relatives, Hallyday is “progressing well”. By far the most famous French rock singer, he has sold in excess of 100 million albums and he is a succesful film actor Doctor Delajoux is reported to have sought medical attention after the attack. He is not thought to be seriously hurt but he has asked for police protection.
