BELGRADE, April 12 (Reuters) - Croatian champions Dinamo Zagreb retained their league title on Saturday after a 2-1 win at bottom team Medjimurje Cakovec left them 19 points ahead of Hajduk Split with six matches remaining.
In Serbia, four fans were injured and 30 arrested after rivals fans clashed ahead of Vojvodina Novi Sad's 1-1 home draw with leaders Partizan Belgrade.
Dinamo clinched their 10th Croatian title to add to the four they won in the former Yugoslavia after first-half goals from Davor Vugrinec and Sammir gave them a 2-0 lead.
Vugrinec turned in a Hrvoje Cale cross from close range in the first minute and Sammir added the second directly from a corner kick before Mario Darmopil pulled one back with a searing drive from 25 metres.
Hajduk stayed second with a 3-1 win at Zadar, where fans and players paid tribute to the home team's winger Hrvoje Custic who died earlier this month after a freak on-pitch incident.
Custic hit a wall by the touchline with his head after chasing a loose ball and died in hospital three days later.
The fans observed a minute's silence, having placed flowers and Custic's shirt on the spot where the incident occurred in Zadar's home game with Cibalia Vinkovci.
Four fans were treated for injuries, one of them for stab wounds, as Vojvodina and Partizan supporters fought running battles in the northern city of Novi Sad before the match.
All four were discharged from hospital after treatment.
Flares and fireworks were also used in the clashes while a local television crew taking footage of the incidents escaped unhurt after it was attacked by the hooligans.
Nenad Djordjevic gave Partizan, who had two players sent off in the second half, a 49th-minute lead before Dusan Tadic grabbed a late equaliser for the home side.
Partizan saw their advantage at the top cut to three points after champions and city rivals Red Star Belgrade beat 10-man neighbours Bezanija 4-1 at home thanks to a Nenad Milijas hat-trick.
The midfielder opened the scoring and rifled in two volleys after Dejan Milovanovic had cancelled out Predrag Randjelovic's equaliser for the visitors, who had goalkeeper Srdjan Ostojic dismissed for a professional foul.
