A Duesseldorf hospital says the co-pilot of Germanwings flight 9525 had been a patient there over the past two months.
Duesseldorf University Hospital said in a statement Friday that Andreas Lubitz last came to the hospital for "diagnostic evaluation" on March 10. It declined to provide details about his condition but denied German media reports that it had treated the 27-year-old pilot for depression.
The hospital says it has submitted Lubitz's patient record to prosecutors in Duesseldorf, where he lived.
Prosecutors say Lubitz deliberately crashed his plane into a mountain in the French Alps, killing all 150 people on board.

Brokaw says "I want people to know they're not alone." He says that after such a crash, families can be deluged with information and questions, and it helps to have a point of contact who can help them sort through it all at a time they're still grieving.
He added: "It's disorienting, it's literally unspeakable there are no words for expressing the total loss."

The parents of 37-year-old Robert Oliver, one of the three American citizens killed in the Germanwings crash, say they are finding solace in memories of their son.
"Instead of focusing our minds and hearts on those last nine or 10 minutes (of the flight), we prefer to think about those 37 years that we've been together," father Robert Oliver Calvo said.
He told reporters in Barcelona that he feels no anger toward co-pilot Andreas Lubitz, accused of crashing the Airbus A320 into the French Alps, killing all 150 people on board.
"I'm really sad for those parents of that young pilot. I can't imagine what they're going through right now," he said.
Robert Oliver worked for a clothing company in Barcelona, where his parents also live.

German prosecutors say they have found evidence that the co-pilot of the Germanwings plan which crashed in the French Alps appears to have hidden evidence of an illness from his employers.
Prosecutors in the western city of Duesseldorf say they seized medical documents from the home of Andreas Lubitz that indicate "an existing illness and appropriate medical treatment."
Prosecutor Ralf Herrenbrueck said in a statement Friday that torn-up sick notes for the day of the crash "support the current preliminary assessment that the deceased hid his illness from his employer and colleagues."
He said the search of Lubitz's home revealed no suicide note or evidence of any political or religious motivation for his actions.

Three Kazakhs who perished in the Germanwings flight were on a European vacation when they made a spur-of-the-moment decision to go to Spain to watch one of soccer's most popular matches.
The vacation to Europe was precious time together for Kazakh couple Erbol Imankulov and his wife Aizhan Isengaliyeva, after he recently moved 700 kilometers (400 miles) from his home city of Ust-Kamenogorsk to take up a job in the coal city of Karaganda.
The diversion to go watch "El Clasico" on Sunday between Barcelona and Real Madrid was a special treat for their 26-year old son, Adil, who was travelling with them.
All three Kazakhs perished in the Germanwings crash from Barcelona to Duesseldorf that killed 150 people on Tuesday.
Adil's sister, 14-year-old Diana, missed out on the trip. She was unable to get a visa.
The co-pilot is suspected of intentionally crashing the plane into a mountain in the French Alps during the Barcelona to Duesseldorf flight.

France's leading pilots union is filing a lawsuit over leaks about the investigation into the Germanwings crash.
Guillaume Schmid, a representative of the SNPL union, said Friday that pilots are angry that information about the dramatic final moments of the flight were reported in the media before prosecutors and others were informed.
After the media reports, a prosecutor announced that cockpit recordings indicate the co-pilot of the Germanwings A320 jet intentionally flew the plane into a mountain on Tuesday. All 150 aboard were killed.
The lawsuit is over violating a French law on keeping information about investigations secret while they are ongoing. The lawsuit doesn't name an alleged perpetrator, a common method in French law that leaves it to investigators to determine who is at fault.
Schmid said that pilots are saddened by the accident and understand the public's wish for immediate information, but decried pressure on investigators and said that can lead to misleading the public instead.

German police have searched the home of co-pilot Andreas Lubitz in Duesseldorf and seized material that will now be examined as part of the investigation into the crash that killed 150 people in the French Alps.
French investigators believe Lubitz locked himself inside the cockpit and then intentionally smashed the Germanwings plane into a mountainside.
A spokeswoman for Duesseldorf police denied reports Friday that the officers had made any significant discovery yet.

The co-pilot who authorities believe intentionally crashed an airplane into the French Alps, killing all 150 people on board, likely first honed his flying skills for months in Arizona.
Lufthansa Group, which owns Germanwings airline, said Thursday that 27-year-old Andreas Lubitz trained in Bremen, Germany, and Phoenix starting in 2008.
A Facebook page bearing his name lists Phoenix Goodyear Airport among his interests. The airport houses Airline Training Center Arizona, a Lufthansa-owned training facility.
Aviation experts say students there log flight hours and attend classes on navigation in an 18-month period. On Thursday, German and Lufthansa flags outside the facility were flying at half-staff.
Sunshine and vast air space have historically made Arizona a popular location for pilot training.
French prosecutors say Lubitz locked the pilot out of the cockpit of Germanwings Flight 9525 on Tuesday before the jet slammed into the mountainside.
