Gleb, a well-known organizer of aerial drone photography, was arrested in September 2021 in connection with a criminal case opened for online comments following the deaths of KGB officer Dmitry Fedosyuk and IT specialist Andrei Zeltser in Minsk. Gleb is known to have left the message "Dimon tu-du-tu" (to the tune of the music from the film "Boomer").
In February 2023, he was found guilty of "inciting hatred or discord," "obstructing the lawful professional activities of a journalist," "insulting a government official," "insulting Lukashenko," and "calls for restrictive measures (sanctions) and other actions aimed at harming the national security of the Republic of Belarus," and sentenced to imprisonment.
On September 11, 2025, it was announced that 52 prisoners of the Belarusian regime had been forcibly transferred to Lithuania, including citizens of European countries. Gleb was among those released.
