The chief of the SBU's main investigation department, Maksym Lenko, said this at a briefing on Saturday, Ukrinform reported. "The information about a crime committed under Article 15 (attempt to commit a crime) and Article 110 (encroachment on the territorial integrity of Ukraine) of the Criminal Code of Ukraine has been included in the unified register of pretrial investigations," he said. He added that the reason for launching the proceedings was a statement filed by Batkivshchyna MP Ivan Stoiko. "The SBU's main office in Crimea was ordered to investigate this crime," he said. The MP earlier demanded that the Security Service of Ukraine and the Prosecutor General's Office take immediate and strict measures to prevent the "deployment of separatism in Crimea."
