The Serbian interior ministry said Tuesday that it will extend "all assistance" to Italian police after rioting fans forced the Euro 2012 football qualifier between Italy and Serbia in Genoa to be called off, dpa reported.
Officials sent the players back to the dressing rooms after just seven minutes as Serbian fans threw flares on the pitch and demolished their section of the stands.
The start of the match was also delayed by over half an hour because of violence.
The interior ministry said that the reported attack by fans on the Serbian goalkeeper Vladimir Stojkovic would be separately investigated, radio-television B92 reported.
According to unconfirmed reports, Serbian hooligans barged into the Serbian team bus as it pulled in front of the Genoa stadium and attacked Stojkovic with flares.
Although five to six hooligans reportedly came at him with torches, Stojkovic was defended by teammates and escaped injury, it said, quoting the Genoa midfielder, Serb Bosko Jankovic.
The Serbian consul general in Italy, Ivana Pejovic, told B92 that Italian authorities were putting the fans on buses and that she has no information of any arrests.
Stojkovic, 27, was targeted by abuse ever since he signed for Partizan Belgrade after the Serbian champions advanced to the European Champions League.
Before becoming a journeyman playing for sides in Portugal, England, France and Netherlands, Stojkovic was on the goal of Partizan's arch-rivals, Red Star Belgrade.
Following the transfer, the 27-year-old said that he received death threats but that he was not concerned.
In the home qualifier against Estonia on Saturday, which Serbia lost 3-1, Red Star fans booed and jeered him on every contact with the ball.
Partizan coach Aleksandar Stanojevic was quoted as saying that he "deeply regrets" the attack on his keeper.
Serbian hooligans have a record of extreme violence. A year ago a visiting French fan was beaten to death ahead of Partizan's UEFA League match against Toulouse.
Fans are also the inevitable ingredient in riots such as Sunday's, when several thousand thugs clashed with police trying to break a gay pride parade.
