The investigation into Michael Schumacher’s skiing accident, which left the seven-time F1 world champion with serious head injuries,  has now been closed, with no further legal action being planned.

A probe was launched last month following the German’s accident in the French Alps at the end of December. Albertville prosecutor Patrick Quincy, the man in charge of the investigation, said on Monday that, “The investigation into the causes and consequences of the December 29 skiing accident of Michael Schumacher…closed on February 12. No person has been found guilty of any violation.”

Schumacher underwent two surgeries and has been in a medically induced coma since the crash. Doctors in the Grenoble hospital where Schumacher is being treated said at the end of last month that they were starting the waking-up process.

“Michael’s family would like to again express their sincere thanks for the continuous sympathy coming from all over the world,” read a statement released by the family. “The good wishes they receive help the family and, we are convinced they also help Michael, who still is in a waking-up process.

“As often in such situation, no day is like the next,” continued the statement. “The family is thankful for one’s understanding that they would not wish to disclose medical details in order to protect Michael’s privacy. As assured from the beginning we will continue to communicate any decisive new information on Michael’s health state. We are aware that the wake-up phase can take a long time.

“The family continues to strongly believe in Michael’s recovery and place all their trust in the doctors’, nurses’ and nursing auxiliaries’ team. The important thing is not the speed of the recovery but that Michael’s heal process progresses in a continuous and controlled way.

F1 teams showed their support for Schumacher during the recent Jerez tests, with Ferrari creating a special pitboard (pictured) and Mercedes running the message ‘#KeepFightingMichael’ on its cars.
