No fan group high risk insist authorities

Austria's director general of public security refused to name particulare nation's fans as a security risk during the tournament but said police were prepared should the mood turn sour.

Austria hosts its first matches of the tournament at the end of the week, when Austria go head to head with Croatia and Germany meet Poland and tens of thousands of fans are expected to travel there.

Erik Buxbaum dismissed suggestions that the Germany versus Poland game could prove a particular trouble hot-spot, after a provocative war of words this week between German and Polish newspapers.

"But we expect people will have let off steam and that sport will be the focal point. We are prepared for a possible tense atmosphere but have no evidence to suggest that we should expect one," Mr Buxbaum said.

Mr Buxbaum added foreign police officers had provided the Austrians with information about known hooligans or trouble makers and some would be working as "spotters" mingling with fans in plain clothes to clamp down on trouble.
