Serbian police arrested two men linked to an alleged attempt to overthrow the government in neighboring Montenegro, the interior ministry said Friday.

Belgrade’s high court released one of the men from custody later Friday but banned him from leaving the city. The other man will remain in custody.

Montenegrin police arrested 20 people, including Russians and Serbians, on the day of an election in October for allegedly planning to carry out attacks to disrupt parliamentary elections.

The state prosecutor in November said "nationalists from Russia” were behind the plot, but Moscow said it had no involvement in the alleged coup attempt.

In November, Montenegro's parliament endorsed a cabinet led by Prime Minister Duško Marković of the Democratic Party of Socialists, replacing former premier Milo Đukanović.
