Ukrainian citizen Hennadiy Lemeshko, who was detained in the occupied Crimea, served in the Armed Forces of Ukraine under a contract and was dismissed in May 2017, the Public Relations Department of the General Staff of the Armed Forces of Ukraine reported.

"This person served in the Armed Forces of Ukraine under a contract from November 2016 to May 2017. He was dismissed under the article 'inaptitude'," the General Staff's representative Yuzef Venskovych told Interfax-Ukraine on Tuesday.

Venskovych said that Lemeshko served in a unit of the Land Forces of Ukraine and dismissed for constant disciplinary violations.

As reported, the Russian Federal Security Service (FSB) announced on Tuesday morning it prevented acts of sabotage against Crimean infrastructure and crucial utilities and detained 'an agent of the Ukrainian Security Service (SBU)'. The Kyivsky District Court in Simferopol ordered a two-month arrest of Ukrainian citizen Hennadiy Lemeshko until September 13, 2017.

The SBU said the detention of the so-called agent is another provocation and a fake peace of news created by Russia to intimidate Crimeans.
