On the eve of 16 October 2016, the day of the
parliamentary election in Montenegro, a group of 20 Serbian and Montenegrin citizens, including the former head of
Serbian Gendarmery Bratislav Dikić, were arrested; some of them, along with other persons, including two Russian citizens, were later formally charged by the authorities of Montenegro with an attempted
coup d'état. In early November 2016, Montenegro's special prosecutor for organised crime and corruption, Milivoje Katnić, alleged that "a powerful organisation" that comprised about 500 people from Russia, Serbia and Montenegro was behind the coup plot. In February 2017, Montenegrin officials accused the Russian 'state structures' of being behind the attempted coup, which allegedly envisaged an attack on the country's parliament and assassination of prime minister
Milo Đukanović. The details about the coup plot were first made public at the end of October 2016 by Serbia's prime minister
Aleksandar Vučić, whose public statement on the matter stressed the role of Serbia's law enforcers, especially the Serbian
Security Intelligence Agency, in thwarting it. The statement was immediately followed by an unscheduled visit to
Belgrade by
Nikolai Patrushev, secretary of Russia's
Security Council. One of the charged, Predrag Bogićević from Kragujevac, a veteran and leader of the Ravna Gora Movement, said that Saša Sinđelić informed him on a possible attack on Serbs who participated in the October 16th protest. Bogićević, in Serbian detention, said through his lawyer that there was no talks whatsoever on a coup and no mentions of Đukanović. The Moscow–based
Russian Institute for Strategic Studies (RISS), which has close ties to Russian
Foreign Intelligence Service (SVR), was mentioned by mass media as one of the organisations involved in devising the coup plot; in early November 2017, Russian president
Vladimir Putin sacked the RISS director,
Leonid P. Reshetnikov, a ranking veteran officer of the SVR.
