A formal legal complaint has been longed by the Switzerland-based air rescue service Rega against an unknown person, after its computer was tracked down for a bid to sell Michael Schumacher's missing medical file.

The ex-F1 champion had suffered a serious head injury in a skiing accident last December in the French Alps. He was then take to the Grenoble hospital from where he was further transferred to University Hospital of Lausanne (CHUV) on June 16 after emerging from a coma state.

Problems arose when the F1 ex-champion's medical files were "clearly stolen" and were being offered for sale so much so that they were available across Europe for 50,000 Euros.

The French daily "Le Dauphine Libere" reported that the IP address of a computer used for biding has been located to a Zurich-based helicopter company.

After this French newspaper report Regan clarified that they have found no evidence against any of its employees. So, no violation has been observed on the part of patient privacy and medical secrecy after receiving Schumacher' medical report from the Grenoble hospital.

"Noting that it was now at the "centre of speculation", said Rega as it was making a public statement to clarify the situation.

On contacting the Zurich cantonal prosecutor it was reported that they had received Rega's complaint but said it had not opened a formal investigation for now.

Schumacher's agent Sabine Kehm said that Criminal charges and damages would be sought against anyone involved in the illegal sale of the seven-time Formula One champion's medical records.
