This was reported by RIA Novosti with reference to the press secretary of the Prosecutor General's Office Eva Bialik.
"Investigative group No. 1 of the Prosecutor General's Office appealed to the District Court of the Warsaw-Mokotov region with a motion for the temporary arrest of three air traffic controllers who served in Smolensk-Severny airport in 2010," she said.
According to her, the accusations of dispatchers relate to "deliberately provoking a plane crash that resulted in the death of many people."
Kaczynski's plane crashed in 2010 while landing at Smolensk-Severny airport.
96 members of the Polish delegation were killed.
The report of the Interstate Aviation Committee says that the immediate cause of the crash was the decision of the crew not to leave for an alternate airfield, but systemic - shortcomings in flight support and crew training.
The Investigative Committee of Russia stated that all the materials collected unconditionally testify to the erroneous actions of the crew, which continued the landing approach in the absence of visibility.
