The Security Service of Ukraine has interrogated Lviv Mayor Andriy Sadovy as a witness in the case on using the map with the self-proclaimed "Donetsk and Luhansk People's Republics" on it at the Lviv Security Forum.

"Investigators of the Ukrainian Security Service branch in Lviv region conducted an interrogation of Lviv Mayor Andriy Sadovy under open criminal proceedings under Part 1 of Article 110 (infringement against the territorial integrity and inviolability of Ukraine) of the Criminal Code of Ukraine," the Lviv regional office of the SBU wrote on its Facebook page on Tuesday evening.

The report stresses that Sadovy was questioned in the presence of a lawyer in accordance with the Code of Criminal Procedure and the interrogation was videotaped.

It is also reported that the video recording of the Lviv mayor's testimony will be attached to the materials of criminal proceedings.

Lviv region's SBU office on December 1 opened a criminal investigation into the matter pursuant to Part 1 of Article 110 of Ukraine's Criminal Code (infringing on Ukraine's territorial integrity and sovereignty).

Lviv Mayor Sadovy was summoned for questioning in this case on Monday, December 4.

Sadovy issued a following comment following his questioning: "… There was a forum in Lviv on security from Wednesday through Friday that generated much interest … During one of the panel discussions moderated by Myroslava Gongadze, a graphic from the European center of international affairs was demonstrated … some people liked it, others did not. A criminal case was opened as a result. Today I spoke with the investigators – five SBU agents – who were tasked with investigating the incident."

According to Sadovy, the case sets a precedent because it is based on a criminal investigation into "an illustration posted on a European website."
