A suspect in the theft of a medical file related to Michael Schumacher has been found dead in his cell, prosecutors have said.
The man worked for the Rega air ambulance service, which organised the Formula One world champion's transport from a French hospital to Switzerland in June.
He was arrested on Tuesday and questioned by police, before being detained in a Zurich jail, according to a statement from the Zurich prosecutor's office.
The man - who has not been named - had denied any wrongdoing.
Prison officers found the man dead when they came to bring him breakfast. He was due to appear at a scheduled hearing before a judge today.
Prosecutors say initial investigations indicate nobody else was involved in the man's death.
Last month prosecutors tracked the IP address of a computer used in the theft of the medical records to the Zurich-based company Rega.
The company denied any wrongdoing and, along with Schumacher's family, pressed charges against "unknown persons" for violating professional secrecy.
The records were stolen and offered for sale to journalists for €50,000.
Schumacher, a seven-time F1 champion, suffered serious brain injuries in a skiing accident in the French Alps on December 29th.
He was reportedly travelling at speeds of up to 60mph when the accident happened.
He spent more than five months in a hospital in Grenoble, before being brought by ambulance on June 16th to a high-tech clinic in the Swiss city of Lausanne.
Schumacher won a record 91 Grand Prix victories during his career. He left motor racing in 2013 after a disappointing three-year comeback.
