The Criminalistics Institute has been and remains a secret institution since its inception. One of the activities of the organization in Soviet times was the production of poisons and means of their covert use. One of the Institute's divisions is still working with poisons. Russian journalist claimed that
polonium was stored in the Institute, which was later used to
poison former FSB officer Alexander Litvinenko. In December 2020, a joint investigation by
Bellingcat and
The Insider, with the participation of
Der Spiegel,
CNN and the
Anti-Corruption Foundation, concluded that the Institute's employees are working with
chemical weapon, in particular, with a
Novichok agent. The same investigative group reported that a team of FSB operatives worked under the cover of the Institute, which organized the assassination attempt on
Russian opposition leader
Alexei Navalny in
Tomsk, and that this team operated under the leadership of Stanislav Makshakov, deputy head of the FSB Criminalistics Institute. == Personalities ==
