Police officers walk next to the apartment believed to belong to Germanwings co-pilot Andreas Lubitz in Duesseldorf March 27, 2015. The German pilot believed to have deliberately crashed a plane in the French Alps killing 150 people broke off his training six years ago due to depression and spent over a year in psychiatric treatment, a German newspaper reported on Friday. The story in German tabloid Bild came a day after French prosecutors said they believed Andreas Lubitz, a 27-year-old co-pilot at Lufthansa's budget airline Germanwings, had locked the captain out of the cockpit and steered the Airbus A320 airliner into its fatal descent.
