The video shows the detention and the search at the detainee's apartment.
The FSB officers captured on camera allegedly found weapons and components for explosive devices, military insignias, visiting card of the Right Sector, a plate with the emblem of a Ukrainian military unit, national symbols of Ukraine, etc.
As reported, the Russian FSB announced detention of another "Ukrainian saboteurs" in annexed Sevastopol Nov. 9. The subversives were allegedly plotting sabotage against sensitive facilities in Crimea.
The Russian law enforcers said the detainees were alleged members of the "subversive-terrorist group of the Main Intelligence Directorate of the Ministry of Defense of Ukraine."
Ukraine's Defense Ministry Speaker Andrii Lysenko denied this information, saying that there were no Ukrainian saboteurs in Crimea while the Federal Security Service of the Russian Federation was trying to mislead everyone again.

Earlier, on Aug. 10, the FSB released an official statement about averted terrorist attacks in annexed Crimea "prepared by the Main Intelligence Directorate of Ukraine's MoD in order to target critical life-supporting and infrastructure facilities inside the peninsula." Further on, the FSB released a video with the alleged organizer of the thwarted "terrorist acts" in the occupied Crimea, Zaporizhia region resident Yevhen Panov.
Russian President Vladimir Putin, in turn, said that Ukraine "has switched to the practice of terror."
Putin also said he considered the upcoming Normandy Four meeting to be pointless in the light of the alleged detention of Ukrainian "saboteur" in occupied Crimea.
Putin's puppet of the so-called "parliament" of Crimea Remzi Ilyasov said the occupying authorities perceive the incident "as an act of aggression, in fact, a declaration of war."
The General Staff of the Armed Forces of Ukraine denied all Russia's allegations, calling them provocative.
National Security and Defense Council Secretary Oleksandr Turchynov described the hysterical and false allegations by Russia's FSB as groundless and called them another element of Russia's hybrid war against Ukraine and an attempt to exacerbate the situation in the occupied territory.
The Ukrainian MoD has refuted the FSB's allegations on the involvement of Ukraine's intelligence in subversive activities in Crimea and called them an attempt of the Russian Federation to justify its aggression in the territory of the annexed peninsula.
President Petro Poroshenko said that the Russian allegations are groundless and serve as "a pretext for more military threats against Ukraine."
Spokesperson to the U.S. Department of State Elizabeth Trudeau said that the Russian Federation's recent allegations on Ukraine's involvement in "subversive activities" in Russian-occupied Crimea should not distract the United States from the real issue Russia has created in Ukraine.
On Aug. 11, President of Ukraine Petro Poroshenko instructed that all the units deployed at the administrative border with Crimea and the demarcation line in the Donbas be on high alert.
Ihor Kotelianets, Panov's brother, claims Yevhen was kidnapped in Ukraine's Zaporizhia region and taken to the occupied peninsula.
According to Ukraine's Defense Intelligence, none of its employees has been detained by the FSB to date in the territory of occupied Crimea.
The police have qualified the fact of Yevhen Panov's disappearance reported by his relatives as a criminal offence under the article 146 (illegal deprivation of freedom or abduction) of the Criminal Code of Ukraine.
First Deputy Chairman of the Verkhovna Rada, Ukraine's representative in the humanitarian subgroup of the Trilateral Contact Group Iryna Herashchenko says Yevhen Panov has become another kidnapped Russian hostage who Ukraine will have to liberate.
