The members of Kosovo special police ROSU unit arrested three Serbs in northern Kosovo early on Friday allegedly linked to the January's assassination of a Kosovo Serb leader Oliver Ivanovic, and one for resisting police, media reported.

The KosSev website journalist Milica Andric told N1 that one of the arrested was a policeman suspended for allegedly hiding evidence in the Ivanovic’s murder case.

Daut Hoxha, the Kosovo police spokesperson, told the website that three people were apprehended in connection with an investigation of the assassination, while one man had to be detained for confronting police officers.

The head of the Serb List, a party supported by Belgrade, Igor Simic, said that the arrests linked to Ivanovic’s murder were “a brutal lie to cover up the intimidation of people.”

“They were all apprehended with use of force, threats and intimidation,” Simic said.

The mayor of northern Mitrovica, a part of the divided town populated by the majority of Serbs, Goran Rakic, said it was yet another kind of pressure on the Serbs and that there would have been a conflict if ROSU hadn’t withdrawn its men.

During the ROSU intervention in Mitrovica the sirens went off, and people came out to the streets.

On Thursday, Serbian President said he had information on Kosovo troops’ movement toward the northern part, but the NATO-led Kosovo Force (KFOR) prevented them.

KFOR later denied any intervention and any troops movements.
