The co-pilot of the Germanwings airplane who deliberately crashed the aircraft in the French Alps in March, saw seven doctors in a month before the crash, officials said.

In the on-going prosecution in Marseilles, in-charge of the judicial investigation of the crash, said Andreas Lubitz, 28, also saw 41 others in five years after he was diagnosed with psychosis, Xinhua news agency reported on Friday. "Lubitz was concerned about his health and feared a loss of his sight, suffering from severe depression and psychosis," Marseilles prosecutor Brice Robin said.

At a meeting with the families' victims in Paris, Robin unveiled that the co-pilot had seen, during the weeks before the crash a general practitioner, three psychiatrists and three ear, nose and throat (ENT) specialists with one of them noted "a suspicious threatening psychosis".

On March 24, the airbus A320, operated by Lufthansa's budget airline Germanwings, crashed while flying from Barcelona, Spain to Duesseldorf, Germany, killing 144 passengers and six crew members on board. Analysis of the plane's two black boxes revealed that Lubitz deliberately destroyed the plane after locking his captain out of the cockpit.

The co-pilot had been working for Germanwings since September 2013 and completed 630 flight hours. He was trained as pilot at Lufthansa' pilot school in the German city of Bremen before he was hired.
