GENEVA (AP) — Switzerland’s Rega air rescue service says it has filed a complaint with Zurich prosecutors to trigger an investigation into Michael Schumacher’s stolen medical files.

The Zurich-based service says an investigation will provide “comprehensive clarity” in the wake of news media reports focusing on Rega’s role in handling the German sports star’s files, which his management says have been offered for sale.

Rega confirmed Tuesday it was provided the files by a French hospital when it arranged for the seven-time Formula One world champion to be transferred to a hospital in Lausanne, Switzerland, last month to continue his recovery from his Dec. 29 skiing accident.

The service says it has no reason to believe any of its employees did anything wrong.
