Serbian journalist, Stefan Cvetkovic, says that his months long investigation into the killing of the Kosovo Serb political leader Oliver Ivanovic, in Mitrovica North, indicate that mafia in the north of Kosovo is to be blamed for his assassination. Cvetkovic said that he came to Kosovo after an invitation by the Kosovo Police to be interviewed related to Ivanovic’s case. Cvetkovic, known for criticizing local authorities, made headlines last week after he was reported missing for two days.
