Russian citizen Yevgeny Yerofeyev's lawyer Oksana Sokolovska views a fire at an office of presiding trial judge Mykola Didyk as a provocation.

"This is another provocation, I can hardly imagine even now, by whom exactly, because, principally, the case is being tried quite productively and reactively, a court session takes place every day now, therefore, this hearing of the case stands in someone's way," Sokolovska told reporters in Kyiv on Friday during a break in the Kyiv Holosiyivsky District Court session addressing the case of Alexander Alexandrov and Yevegeny Yerofeyev, commenting on the overnight fire which occurred at the office of the judge presiding in the trial.

Additionally, she said that she did not believe in any accidents. "There are so many events connected to this case. And I do not believe that the 'Molotov [incendiary] cocktail' was hurled into Didyk's office by chance," the lawyer said.

In response to a question as to whether this will affect the progress of the court hearings, Sokolovska said that all the materials, which are evidence in this case, had not been stored at Didyk's office; therefore, this fact will in no way impact the progress of the trial.

Speaking about whether it is possible to view this as pressure on the presiding judge, the lawyer said: "It is quite probable."

Overnight into Friday, unidentified offenders hurled a bottle containing a highly flammable mixture at an office of the Holosiyivsky District Court. Fire broke out in the office of Judge Didyk. The documents in the case against the Russians were not damaged.

On May 16, 2015, Russian security officers A. Alexandrov and Ye. Yerofeyev were detained near the town of Schastia, Luhansk region of Ukrainein an attempt to seize a strategic bridge.

On May 19, Ukrainian detectives told the Russians that they were suspected of crimes stipulated under Article 258-3 of the Ukrainian Penal Code for involvement in terrorist activities. The Kyiv Shevchenkivsky District Court ordered their arrest on May 22.
