UEFA has opened disciplinary proceedings against Croatia following the crowd trouble during their 2-2 draw with the Czech Republic in their Euro 2016 clash in Saint-Etienne on Friday.
Flares were thrown on the pitch and fighting broke out in the Croatian end during the Group D contest with referee Mark Clattenburg being forced to suspend the game with four minutes remaining, while a steward was almost hit by a firecracker, as was Croatian goalscorer Ivan Perisic.
The Croatian Football Federation has been charged with setting off of fireworks (Article 16 (2) of the UEFA Disciplinary Regulations (DR)), throwing of objects (Art. 16 (2) DR), crowd disturbance (Art. 16 (2) DR) and racist behaviour (Art. 14 DR).
The racist behaviour charge comes after UEFA's anti-discrimination monitors - the FARE Network - revealed they had told tournament organisers about alleged fascist songs and banners allegedly waved by Croatia fans during the game.
He said: "These people are really scary, that is why I call them hooligans. These are not really Croatian supporters. These are sports terrorists. The main thing is our country doesn't want to mess with this kind of hooligans.
"This is maybe just a question about six to 10 individuals. I hope they can be identified and punished. I hope the Croatia FA is doing everything to prevent this, but it is impossible to avoid.
"Ninety-five per cent of our supporters are ashamed in front of Europe, the players are very sad that after playing a beautiful match, this happens."
Croatia's president Kolinda Grabar Kitarovic appears ready to act on Cacic's call after calling for a government meeting to discuss the trouble at Euro 2016
Grabar Kitarovic, evoking for the first time her constitutional right to call urgent government meetings, said the country must adopt new stricter laws against hooliganism in the sport.
The Croatian federation has a chequered recent disciplinary record.
Flares were hurled onto the pitch during a European Qualifier against Italy in November 2014 and the team were ordered to play the return match against the Italians in June 2015 behind closed doors as punishment for racist behaviour during a match against Norway two months earlier.
But even the stadium ban did not prevent disturbance, with a swastika being drawn on the pitch in Split before the Italy match.
UEFA reacted by docking Croatia one qualifying point, ordering them to play two further matches behind closed doors and issuing a 100,000 euro fine.
Barcelona midfielder Ivan Rakitic fears the team could now be thrown out of Euro 2016 after the crowd trouble.
"We have to see if we will play against Spain, maybe they will send us home after this," he told HTV.
"There are a lot more fans that love the national team and they will not be able to see Croatia play. It is hard to say, but we feel more comfortable playing away... we were lucky that the match went on, the referee wanted to end it immediately."
Russia have already been handed a suspended disqualification from the tournament, which will be activated if their supporters are involved in any more trouble, following disturbances at the end of their match against England at the Stade Velodrome on June 11.
Disciplinary proceedings have also been opened against Turkey following their 3-0 defeat to Spain in Nice on Friday evening.
There was a series of loud bangs after the final whistle at the Stade de Nice, with fans lighting up flares.
The charges against the Turkish Football Federation are setting off of fireworks, throwing of objects and field invasion (Art 16 (2) DR).
The cases will be dealt with by the UEFA Control, Ethics and Disciplinary Body on Monday.
