A man arrested on Tuesday suspected of involvement in the theft and leaking of a medical file on injured ex-Formula One champion Michael Schumacher was found hanged in his cell Wednesday, prosecutors said.
The man, whose identity was not disclosed, worked for a Swiss helicopter air rescue company, Rega, which organised the sportsman's transport from a French hospital to Switzerland in June, the Zurich prosecutor's office said in a statement.
The cantonal prosecutor said it had found no indication that a third party was involved in the death of the man.
Schumacher, who suffered severe head injuries in a ski accident in the French Alps last year, was transferred under a pseudonym from Grenoble hospital to University Hospital of Lausanne (CHUV) on June 16 after emerging from a coma.
The 45-year-old German was taken by ambulance but Rega was also contacted when helicopter transport was being considered.
The French daily "Le Dauphine Libere" reported in early July that leaked documents being offered to European media for some 60,000 Swiss francs ($67,200) appeared to have come from the IP address of a computer at a Zurich-based helicopter company.
