Zagreb County Court investigating judge Ratko Scekic is likely to consider the motion for detention on Thursday.
The Croatian police launched the investigation dubbed Offside in late 2009 after receiving information from German police about match fixing and related betting scams in Croatia.
A total of 19 First Division players and officials plus three men believed to have organised betting fraud -- Vinko Saka, Dino Lalic and Admir Suljic -- are under investigation.
Those three masterminds "earned" between EUR 150,000-300,000 per fixed match.
Interior Ministry spokesman Krunoslav Borovec said today the investigation was going on in cooperation with other European countries, but declined to cite which countries were also probing match-fixing scandals, explaining that similar investigations were under way there.
Borovec announced more arrests in the coming days, and praised the Croatian Football Federation for good cooperation in the probe.
USKOK suspects that matches of Croatia Sesvete with Zadar, Slaven Belupo, Rijeka, Zagreb and Cibalija were fixed after that club, based in Zagreb's suburb of Sesvete, stood no chance of surviving in the First Division.
A statement which the Croatian police issued on Tuesday reads that the Croatian police are cooperating with their colleagues in Germany and other European countries in investigating similar cases abroad.
A broad international investigation was launched late last year after German police arrested 15 people, including the Croatian-born brothers Ante and Milan Sapin, of Berlin, who had been convicted for match fixing in Germany in 2005.
The European football governing body UEFA said at the time that most of the 200 suspicious matches concerned nine European football leagues, and that 14 Croatian First Division matches were suspicious.
