The co-pilot of Germanwings Flight 9525 that crashed into the French Alps last week had received treatment for suicidal tendencies several years ago, prosecutors said.
Ralf Herrenbrueck, a spokesman for the Düsseldorf prosecutors, said Andreas Lubitz had received psychotherapy treatment "with a note about suicidal tendencies" for a number of years before becoming a pilot. But after qualifying, Lubitz had not received similar treatment.
"There is no evidence to show that the co-pilot was about to do what he appears to have done," Mr Herrenbrueck said, adding that there was nothing so far in Lubitz's "personal and professional life that can enable us to say anything about his motive".
A spokeswoman for Lufthansa, the parent company of Germanwings, said medical records were subject to doctor-patient confidentiality and that the airline therefore had no knowledge of what they contained.
