Doric told a news conference on Wednesday that since 2000, when there were only some 30 arrest warrants issued in Serbia for Croatian citizens, that figure had climbed to 186 in 2009.
He criticised the Office of the Chief State Prosecutor (DORH), the Supreme Court and the Interior Ministry for having met only once in those nine years.
It is evident that our authorities are sloppy, but Serbia too has not published the exact number of people it is searching for, Doric said at the news conference organised by the HNS parliamentary group.
He said that he received information from the Council of Europe that Serbia had issued warrants for the arrest of four Croatians, although today this figure was much higher.
HNS parliamentary club chair Vesna Pusic said that the Purda case had nothing to do with Croatia's European Union membership bid.
She stressed, however, that bringing into order the system of war crimes prosecution did have an impact on Croatia's efforts to join the EU.
In response to reporters' question whether Purda was betrayed by the Croatian authorities as they had known about Serbia's warrant for his arrest in 2007, Pusic said that the authorities should have already dealt with the case, establish what it was about, and clear it up in court proceedings.
