 (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. 
 
 Schumacher has been undergoing hospital treatment since a skiing accident last year but is now out of a coma. 
 
 Manager Sabine Kehm said the documents had been offered for sale for several days. 
 
 She added, "We cannot judge if these documents are authentic. However, the documents are clearly stolen. The theft has been reported. The authorities are involved." 
 
 Medical files are confidential, and it is forbidden to buy or publish such data, Kehm said. 
 
 "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," she said. 
 
 Schumacher, 45, suffered severe head trauma in a December 29 skiing accident at the French Alps resort of Meribel. 
 
 The champion driver, from Germany, was transferred last week to Switzerland for rehabilitation from a hospital in Grenoble, France, where he was kept in a medically induced coma for more than three months. 
 
 The Grenoble hospital's media office said in a statement that Kehm "told us that a person intended to sell to the press a document allegedly issued from the medical records of Michael Schumacher." 
 
 "Without knowing the precise nature of the document, the Grenoble Hospital decided to sue for 'theft and breach of medical confidentiality' so that an investigation can be initiated." 
 
 A spokesman for the German newspaper Bild, Tobias Frolich, told CNN that the tabloid was among a number of media outlets to be offered Schumacher's alleged medical records, but that "the editorial office decided to reject the offer." 
 
 A French prosecutor investigating the accident concluded that speed was not behind the fall suffered by the seven-time world champion, whose F1 career ended in 2012.

 Chief anesthesiologist Jean-Francois Payen told reporters that Schumacher was still in a medically induced coma and doctors were focusing only on his current condition. 
 
 "We cannot predict the future for Michael Schumacher," said Payen, who is also in charge of Grenoble University Hospital's intensive-care unit. 
 
 "He is in a critical state in terms of cerebral resuscitation," he added. "We are working hour by hour." 
 
 Schumacher, the most successful driver in Formula One history, arrived at the Grenoble hospital a day earlier already in a coma and immediately underwent brain surgery. 
 
 The German driver was skiing with his son Sunday morning in the French Alpine resort of Meribel when he fell and hit the right side of his head on a rock. He was wearing a helmet, but doctors said it was not enough to prevent a serious brain injury. 
 
 Gerard Saillant, a trauma surgeon who operated on Schumacher when he broke his leg in a 1999 race crash, was at the hospital as a visitor. He told reporters that Schumacher's age — he turns 45 on Jan. 3 — and his fitness should work in his favor. 
 
 But the Grenoble medical team was being very cautious about Schumacher's prognosis. Working to relieve the pressure on his brain, they lowered his body temperature to between 34 and 35 degrees Celsius (93.2 to 95 degrees Fahrenheit) as part of the medically induced coma. 
 
 The neurology team at Grenoble University Hospital is recognized as among the best in France and the hospital, in a city that is the gateway to the French Alps, sees a large number of skiing accidents every year. 
 
 Schumacher has been seriously hurt before. He broke his leg in a crash at the Silverstone race course in 1999. He also suffered serious neck and spine injuries after a motorcycling accident in February 2009 in Spain. 
 
 The area where Schumacher was skiing is part of a web of trails that slice down through a vast and, in parts, very steep snowfield. Although challenging, the snowfield is not extreme skiing. The runs are broad and neatly tended, and the ungroomed area in between, known as off-piste — where the resort said Schumacher was found — is free of trees. 
 
 The resort said Schumacher was conscious when first responders arrived, although agitated and in shock. But Payen said Monday that after the fall Schumacher was not in a "normal state of consciousness." He was not responding to questions and his limbs appeared to be moving involuntarily. 
 
 He was airlifted to a local hospital and then later brought to Grenoble. Doctors said that stopover was typical and did not affect his condition. 
 
 His wife and other family members were by his bedside. 
 
 "The family is not doing very well obviously. They are shocked," said his manager Sabine Kehm, who added that the family still appreciated the outpouring of support. 
 
 The French prosecutor in Albertville has opened an investigation into the accident, according to the Mountain Gendarmerie in Bourg-Saint-Maurice, which will participate in the probe. The goal is to determine the circumstances of the accident and what was responsible for it. 
 
 Formula One drivers and fans rushed to wish Schumacher a quick recovery. 
 
 "Like millions of Germans, the chancellor and members of the government were extremely dismayed when they heard about Michael Schumacher's serious skiing accident," German Chancellor Angela Merkel's spokesman, Steffen Seibert, said in Berlin. 
 
 Sebastian Vettel, for whom Schumacher was a boyhood idol, told German news agency dpa: "I am shocked and hope that he will get better as soon as possible." 
 
 Ferrari, which Schumacher raced for, expressed its concern in a statement. 
 
 "Everyone at Ferrari has been in a state of anxiety since hearing about Michael Schumacher's accident," it said, adding that company president, Luca di Montezemolo, and race team leader, Stefano Domenicali, were in contact with the family. 
 
 British former world racing champion Jenson Button said posted that his "thoughts are with Michael Schumacher at this tough time. ... Michael more than anyone has the strength to pull through this." 
 
 During his career, Schumacher won seven drivers' championships and 91 race wins. After initial success with the Benetton team, Schumacher moved to Ferrari and helped turn the Italian team into the sport's dominant force. After initially retiring in 2006, he made a comeback in 2010 and raced for three years with Mercedes.

– 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.
