Michael Schumacher update features the Formula One legend's allegedly stolen medical records and the possibility that the documents were photographed, reports say.

According to "Schumi's" manager Sabrine Kehm, in a report by CNN, the theft of Michael Schumacher's records has already been escalated to authorities.

"For several days stolen documents and data have been offered for sale," Kehm said, speaking about the Michael Schumacher update. "We cannot judge if these documents are authentic. However, the documents are clearly stolen."

"The theft has been reported," she added. "The authorities are involved."

A week ago, several reports regarding the 45-year old Ferrari driver's medical records have also surfaced. This time, it specified how much the aforementioned documents were priced and offered for sale online, according to French police.

"The perpetrator or perpetrators of the theft contacted some French, Swiss and German journalists," said Grenoble prosecutor Jean-Yves Coquillat in an interview with The Associated Foreign Press about the Michael Schumacher update.

"An individual, communicating by email, is asking for 60,000 Swiss francs (49,000 euros, $67,000) to provide a document of several dozen pages that summarizes everything that happened at Grenoble during Michael Schumacher's hospitalization," he continued.

The medical records in question are that from Michael Schumacher's accident in December 2013, where he hit his head on a rock while skiing with his son in the French Alps.

The documents contain all of "Schumi's" treatment procedures and progress reports since the time of the accident, specifically right after he was airlifted from the scene.

Kehm reiterated the confidentiality of the said records, adding that they will be taking legal action on the matter.

"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," Kehm restated.

Fortunately for the Schumacher camp, the Grenoble Hospital in France, where the Formula One Legend was housed for the initial part of his treatment, has also decided to pursue the perpetrators.

"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," the hospital said in a statement.
