A source in the law enforcement agency told RIA Novosti, Censor.NET reports.
According to the source, the detainee is allegedly a member of the Main Intelligence Directorate of the Ministry of Defense of Ukraine.
"A handgun, grenade, and components for improvised bomb were seized," the source said.
As reported, the Russian FSB claimed apprehension of "Ukrainian saboteurs" in Crimea Nov. 10. The court imposed two months of pretrial custody against them. The footage of the suspects' interrogation was published later. They pled guilty and confirmed their membership in the Ukrainian intelligence agency. The Security Service of Ukraine said the Russian special services intended to discredit Ukraine by making false statements on plotted "sabotage" in the occupied peninsula.
