His car was torched at around 4am in front of a pharmacy in northern Mitrovica. The police considered it a case of arson, the Kosovo Police Service's deputy commander, Besim Hoti, said.
Ivanovic said he did not believe ethnic Albanians were behind the torching, and asked the municipal authorities in the mostly Serb-populated town to condemn the attack.
"Someone obviously doesn’t like the fact that Dragisa Milovic has been meeting Oliver Ivanovic ... Maybe they felt that someone was disturbing the 'idyllic' state we currently have in the northern municipalities," Milovic said.
He added that the Serbian government’s Office for Kosovo had paid a lot of money to install security cameras, which did not work on the night of the attack.
"If the Kosovo Police Service does not uncover the perpetrators who torched our cars, I will consider this a coordinated action between certain criminals and the police", Milovic said."

Serbia government statement in 2017 on slain politician Oliver Ivanovic: "if you vote Oliver Ivanovic, you vote for destruction of Serbian unity in Kosovo, and clearly, you vote against keeping the organic connection between state of Serbia with Serbian people in province"
Murdered #Kosovo Serb leader Ivanovic gave a telling interview few months ago in @NedeljnikVreme: "Nowadays Kosovo Serbs don't fear Albanians. They fear other extreme Serbs, which is why they are moving out of #Kosovo."
