Switzerland-based air rescue service Rega has lodged a legal complaint after its computer was apparently linked to a bid to sell Michael Schumacher's missing medical file.
In a statement, Rega said it had asked Swiss prosecutors to investigate, as it believed its staff were not involved.
The ex-F1 champion suffered a head injury in a skiing accident last December and was moved to a Swiss hospital from a hospital in Grenoble, France, last month. His records were allegedly stolen and offered for sale to several newspapers, the BBC reports.
Schumacher's manager, Sabine Kehm, said last month that the F1 ex-champion's medical files had been "clearly stolen" and were being offered for sale. The records were apparently being offered to media across Europe for 50,000 Euros.
Kehm has warned that criminal charges would be pressed if such "confidential files" were bought or published.
