Montenegrin police arrested an opposition leader early Friday morning for refusing to testify in a case of alleged bribery before the Special Court, and the Podgorica Higher Court ordered two-month detention for Nebojsa Medojevic, the local Vijesti daily reported.

Medojevic, one of the leaders of the opposition Democratic Front (DF), was arrested on the way home after leaving the Parliament at around 2 am.

“The Court issued the arrest warrant after this person’s public claims that he knew that the former Podgorica mayor would not be detained because the main prosecutor took a 100,000 Euro bribe,” a statement from the police said.

Meanwhile, Podgorica's Higher Court said it had issued an arrest warrant for Milan Knezevic, also from the DF, suspected of avoiding to reveal details about a judge who allegedly offered him to annul the verdict for an attack on a police officer in 2015 in exchange for 10,000 Euros.

Slaven Radunovic told reporters he was in a car with Medojevic when police stopped them and took Medojevic away.

He was taken to a local prison.

Another DF leader, Andrija Mandic, said that following Medojevic’s arrest, Montenegro was “on the brink of civil war.”

He told reporters Medojevic was detained “because he did not want to testify as they wished him to,” but he did not elaborate.

Mandic, who said the party would demand a meeting with President Milo Djukanovic, added that another police vehicle waited for DF parliamentarian Knezevic “to arrest him as well.”

Knezevic stayed inside the parliament building with other party members.
