Medical records belonging to seven-time Formula One world champion
Schumacher, who suffered a severe head injury in a skiing accident in December, last week was transferred from a hospital in Grenoble, France, to Lausanne, Switzerland, after waking from a drug-induced coma lasting several months.
The statement said records purported to be Schumacher's medical file have been up for sale for "several days." The statement said authorities are looking into the matter and that appropriate action would be taken if the actual records are made public.
"We cannot judge if these documents are authentic," the statement read. "However, the documents are clearly stolen. The theft has been reported. The authorities are involved.
"We expressly advise that both the purchase and the publication of such documents and data is forbidden."
Little is known about Schumacher's condition. His management team has only confirmed that he is no longer in a coma and that he has begun a "long phase of rehabilitation."
