Nine policemen were injured and two football fans were arrested in clashes with dozens of Hajduk Split supporters after the club had lost a derby match against arch rivals Split, police said Sunday.
The riots erupted after Saturday's late match that Split won 2-1, as several dozen Hajduk Split hardcore fans -- known as Torcida -- attacked police officers and Split supporters leaving the stadium, a police spokeswoman told AFP.
They threw bottles, stones and torches, damaging several vehicles, including two police cars, destroyed two traffic signs and demolished a bar, she added.
The group was among some 500 Hajduk Split fans, who boycotted the match to protest the high prices of tickets and camped outside the stadium during the game.
Police were searching for other fans believed to have been involved in the violence, the spokeswoman said.
Saturday's match was the first in charge for former international defender Igor Tudor who took over as Hajduk Split coach on Monday.
The club from the central coastal town of Split are currently fifth in the national league.
