 (CNN) -- Stolen medical files that may be those of Michael Schumacher are being offered for sale, the injured former F1 racing driver's manager said. Sabine Kehm, the seven-time champion’s manager, said that stolen documents and data had been offered for sale for several days 
 
 “We cannot judge if these documents are authentic. The files are thought to have been stolen from his hospital in Grenoble. The theft has been reported. The authorities are involved,” said Ms Kehm. The contents of any medical files are totally private and confidential and must not made available to the public. “ 
 
 “We will therefore, in every single case, press for criminal charges and damages against any publication of the content or reference to the medical file.” 
 
 The 45-year-old has been in hospital for nearly six months after his accident skiing off-piste on the French Alpine resort of Meribel in December. The stricken Formula One legend, who sustained life-threatening injuries in a skiing accident six months ago, was moved from Grenoble to University Hospital Lausanne in France last week after it was announced he was no longer in a coma.
– Michael Schumacher's medical files have been stolen from a hospital in France and are being offered for sale to the media, the F1 champ's manager warns. The files taken from a hospital in Grenoble where Schumacher spent months in a coma after a skiing accident last December contain details of surgical procedures and are being offered for close to $70,000, according to the Telegraph. The manager says while it's not clear if the documents on offer are authentic, they have clearly been stolen and, since it is illegal to buy or publish confidential medical data, she will "press for criminal charges and damages against any publication of the content or reference to the medical file," CNN reports. The 45-year-old racing legend finally emerged from his coma earlier this month and is now undergoing rehabilitation in Switzerland.
