Investigators may be even closer to solving the theft of Michael Schumacher's medical records.
The Swiss newspaper Sonntagsblick reports that investigators are now looking elsewhere, having found that the doctor's letter was not taken or copied by staff of the university hospital in Grenoble, where Schumacher was in a coma.
Instead, French police are reportedly now looking across the border, into Switzerland, Sonntagsblick claims.
It is believed chief prosecutor Jean-Yves Coquillat suspects that it was during Schumacher's recent two-hour ambulance transfer between Grenoble and Lausanne that the medical summary was photographed.
The ambulance company is reportedly located in the Swiss canton of Valais, and a spokesperson said: "We have decided not to take a public position on the case of Michael Schumacher."
