Two unidentified persons have thrown rocks at the family home of a 38-year-old Serb man in the village of Ostrovica near Benkovac, inland from the coastal city of Zadar, the Zadar Police Department reported on Tuesday.
The attack occurred between 0230 and 0300 hours on Tuesday.
The two attackers also assaulted two elderly residents of Ostrovice, one aged 70 and the other aged 79. Both victims of the assault are ethnic Serbs and both were slightly injured.
Pupovac told a news conference that this kind of violence was taking place because state bodies, police and the judiciary were not doing their job.
"Primarily because they refuse to admit that this is ethnically-motivated violence and attacks on returnees," Pupovac said, stressing that those attacks were exclusively ethnically motivated.
"I do not want to underestimate the meaning of violence against animals, but at the same time we are putting up with the fact that we are living in a country in which a certain number of people cannot tolerate other nations ten years after the end of the war," he said.
Pupovac said he was not surprised because state bodies were not investigating other cases either. According to him, even though police and the State Prosecutor's Office know who planted explosive devices in Borovo Selo and Trpinja in May, they did not bring the perpetrators to justice.
He said he discussed the case with former interior minister.
