"N. Gaiduk was detained while crossing again from Poland into the Kaliningrad region to conduct acts of sabotage against energy objects. After his car, a Ford Focus was inspected... 16.9 ounces of liquid explosives were seized," the FSB said, adding that the detainee, born in 1967, is a resident of Hamburg.
A criminal case has been opened against Gaiduk on charges of committing a terrorist act and smuggling explosives, the federal security agency said, adding that he is currently in custody.
"At the moment, measures are being taken to identify and prosecute persons who assisted N. Gaiduk in carrying out illegal activities," the FSB said in a statement.
The detainee was also involved in an explosion at a gas distribution station in Kaliningrad in March 2024, when he attempted to use a homemade explosive device to blow up a low-pressure pipe at the station in question, the statement said.
"It was determined that the order for staging the explosion, along with military bomb components, was received by Gaiduk from Alexander Zhorov, a Ukrainian citizen born in 1967 who resides in Hamburg under a German residence permit," the report added.
