Police temporarily detained about 200 people throughout Austria on the country's first day of European Championship matches.
Euro 2008 Interior Ministry spokesman Konrad Kogler said the bulk of Sunday's detentions _ about 160 of 206 _ were made in the southern city of Klagenfurt, where Germany defeated Poland 2-0. The match had been billed as one of the more likely for fan violence.
Four of the hooligans detained in Klagenfurt are still in custody, Kogler said Monday. All are German nationals. About 140 people were detained in the southern city late Sunday for shouting Nazi-like slogans.
In Vienna, where Croatia defeated Austria 1-0, eight people were detained for a series of different offenses, Kogler said.
In all, an estimated 270,000 supporters took part in celebrations throughout the country.
"Police guaranteed a safe soccer day yesterday through rapid and reasonable intervention," Kogler said.
Wolfgang Rauchegger, senior police official in Carinthia province, said 157 people were detained in Klagenfurt, including 144 Germans, 10 Poles, two Austrians and one Slovenian.
In total, about 3,000 police officers were on duty throughout Carinthia on Sunday, including 400 from neighboring Germany, Rauchegger said in a local government press release. Most of the officers _ 2,500 _ were on duty in Klagenfurt, he added.
Mayor Harald Scheucher said tens of thousands of fans took part in the city's celebrations.
"It was a great soccer fest with 80,000 fans in Klagenfurt, including 30,000 Poles, 25,000 Germans and 5,000 Croatians," Scheucher said.
