WARSAW, October 31 - RAPSI. After investigating the Polish presidential plane crash, which occurred near Smolensk in April, 2010, the Polish Prosecutor's Office found no traces of explosives at the site, Warsaw's Chief Military Prosecutor Ireneusz Szelag said on Tuesday.

Szelag issued a statement after a Polish newspaper reported that during a second inspection, experts from the prosecutor's office found traces of TNT and nitroglycerine on 30 passenger seats and in the sections where the plane's wings connected with the fuselage. Remnants of explosives were also reported to have been found on the ground.

This claim does not correspond with the official version of the crash.

Szelag said that a group of 11 individuals worked in Smolensk from September 17 to October 12, including a prosecutor from the Warsaw prosecutor's office, bomb experts and plane construction specialists.

He said that experts used equipment that detects substances which have a similar chemical composition to explosives.
The newspaper has since admitted its mistake.

Polish President Lech Kaczynski died in the crash on April 10, 2010, when the Polish Air Force Tu-154 attempted to land at Smolensk-North airport in Russia. 96 people died, including the president, his wife, and a number of the country's key officials.

The Interstate Aviation Committee (IAC) issued a final report in late July 2011 stating that the crash was caused by the crew's attempt to land in thick fog in conditions of poor visibility. Additionally, the IAC said the poor flight preparation and the inadequately qualified crew were the root cause of the tragedy.

In late January, the Prague District Prosecutor's Office said the flight security level did not comply with the rules then set forth by the Government Protection Bureau. Experts revealed that the individuals responsible for organizing Kaczynski's visit to Smolensk committed a number of violations that adversely affected the security of Poland's highest military and civilian leaders.
