Michael Schumacher’s manager Sabine Kehm has warned about “invalid” health reports, after one was quoted as saying the F1 champion’s life was no longer at risk.
Michael Schumacher, 45, remains “critical but stable” in hospital in Grenoble after a skiing accident.
A statement from Sabine Kehm said reports not from managers or doctors “must be treated as pure speculation”.
The statement also rejected reports a camera fixed to Michael Schumacher’s ski helmet had not been handed over voluntarily.
Michael Schumacher, who retired in 2012, is in a medically induced coma after suffering head injuries during a fall in the resort of Meribel last Sunday.
His helmet cracked on impact when he hit a rock while skiing off-piste.
Sabine Kehm’s statement read: “Michael’s condition remains critical but stable. We would like to clearly stress that any information regarding Michael’s health not coming from the doctors treating him or from his management must be treated as invalid and pure speculation.”
“The family cares only for Michael’s health.”
On Friday, some media quoted Michael Schumacher’s friend, former F1 driver Philippe Streiff, as saying that he had been told by the Schumacher family doctor, Gerard Saillant, that Michael’s life was no longer in danger.
Sabine Kehm’s statement continued: “Michael’s helmet camera was voluntarily given to the investigating authorities by the family. That this should have been done against the wishes of the family is untrue.”
Investigators in France are examining the camera.
The French authorities are hoping the device may reveal clues about the circumstances of the accident, although it remains unclear whether the camera was switched on at the time.
Police also interviewed Michael Schumacher’s teenage son, who witnessed the crash.
Michael Schumacher management’s statement concluded by saying: “In consultation with the doctors treating Michael, it is not expected that there will be any press conference before Monday.”
