FSB officers force citizens living in annexed Crimea to cooperate with them in order to collect information about pro-Ukrainian residents of the occupied peninsula. Press service of the Security Service of Ukraine (SBU) reported on the situation. According to law enforcement agencies, the proposals are primarily received by employees in the field of Internet services. They are required to confidentially illegally collect personal data, report on the content on social networks and other personal information of users. The data is further used by Russian special services to prosecute local residents disloyal to the occupation authorities and Russian politics. Ukrainian counterintelligence also discovered that a representative of the FSB of the Russian Federation, a former officer of the Main Directorate of the Security Service of Ukraine in the Crimea, Dmitry Karelin, who in 2014 changed the oath and sided with Russia, was actively involved in this illegal activity. The Security Service of Ukraine warns that defection in conditions of martial law or during an armed conflict, espionage, rendering assistance to a foreign state, foreign organization or their representatives in carrying out subversive activities against Ukraine is punishable by deprivation of liberty for a term of ten to fifteen years. On October 15, a Kremenchug court in the Poltava region of Ukraine sentenced a 57-year-old resident of the city who was recruited during his stay in Crimea to 12 years in prison, finding him guilty of treason in favor of Russia. On September 30, the FSB of Russia attempted to persuade a citizen of Ukraine to tacit cooperation, which would imply collecting and transmitting information about the Armed Forces and volunteer forces at the administration border with the illegally annexed Crimea.
