WARSAW (Reuters) - A Polish military prosecutor shot himself on Monday after cutting short a news conference in which he had defended a military investigation into leaks related to a plane crash that killed Poland's president two years ago.

Local media said military prosecutor Mikolaj Przybyl was taken to a hospital after reporters found him lying on the floor of his office in a pool of blood only seconds after the departing journalists heard a gunshot coming from his office.

Przybyl had asked the reporters to leave his office after he criticised media leaks from the continuing probe into the plane crash in Russia on April 10, 2010, that killed then-president Lech Kaczynski and 95 others, mostly senior Polish officials.

Several news outlets showed footage of Przybyl's body behind his desk before an ambulance took him to a hospital.

A spokesman for the military prosecutor's office was not available for comment. Broadcaster TVN quoted a military spokesman as saying that Przybyl's life was not in danger.

Polish President Bronislaw Komorowski said in a statement he was "concerned" about the suicide attempt and asked the head of the national security bureau to monitor the situation.

During his brief news conference, Przybyl said the military prosecutor's office in the western city of Poznan had the right to seek phone records of journalists covering the investigation of the 2010 air crash.
