Russia's Federal Security Service arrested a man in Crimea on April 22 on suspicion of treason for allegedly handing over secret information to Ukraine about Russia's Black Sea Fleet. Reuters reported this on Thursday.
According to the news and media division, the arrest comes amid acute tensions with Ukraine as Moscow has built up military forces near their shared border. Russian Defence Minister Sergei Shoigu arrived in Crimea on Thursday to oversee large-scale military drills.
The man, who was not identified by name, was arrested in Sevastopol for allegedly gathering and handing over secrets to Ukrainian military intelligence about the Russian fleet that is based on the Black Sea, the security services were cited as saying.
As it was reported earlier, occupied Crimea's Dzhankoy District Court sentenced Yevhen Dobrynsky, a soldier of the Armed Forces of Ukraine. The serviceman was sentenced to thre years and six months in prison for allegedly illegally crossing the state border of the Russian Federation and smuggling drugs.
