The area has been cordoned off to prevent media access.Schumacher, the most successful F1 driver of all time, has had several brain operations since his fall in the resort of Meribel and is expected to face a long recovery.MEDICAL FILES STOLENSchumacher's agent, Sabine Kehm, said on June 2014 that medical records purported to be his had been offered for sale and officials were investigating the theft. Criminal charges and damages would be sought against anyone involved in the illegal sale or publication of his confidential records, she said at the time.
