Ministry spokesman Zlatko Mehun told Hina that Croatia received the news of Suljic's arrest through international police cooperation.
"Suljic was arrested in The Hague as part of an international search launched some time ago. During the arrest, he sustained injuries and was placed under medical supervision," Mehun said.
He added that the Croatian police were ready to bring Suljic to justice as soon as "his condition and other circumstances" allowed it.
Hina could not obtain information on the nature of Suljic's injuries, how he sustained them or where he has been hospitalised.
Officials at the Ministry did not have information on what Suljic had been doing in the Netherlands either. "We are still expecting information on the circumstances of his stay and other details from our Dutch colleagues," Mehun said.
The Justice Ministry has been informed by Interpol about Suljic's apprehension, but official information on his arrest has still not arrived from relevant Dutch judicial bodies, Mehun said.
The international warrant for Suljic's arrest was issued last year after the announcement of a non-final verdict in a repeated trial for crimes committed in Pakracka Poljana. Although he attended court hearings, Suljic did not attend the announcement of the verdict, nor did another indictee, Igor Mikola.
Suljic, Mikola and Sinisa Rimac were convicted of murdering a man.
Mikola and the two remaining members of the group - Miroslav Bajramovic and Branko Saric - were also convicted of unlawful detention and extortion of there Serb men from Zagreb in late 1991.
In late May this year the Supreme Court almost entirely upheld the sentencing verdict of the Zagreb County Court in the case and increased Suljic's prison sentence from 10 to 12 years.
