Football hooligans who marred Tuesday’s Poland-Russia Euro 2012 match with violent clashes in Warsaw must feel the full force of the law, Polish Foreign Minister Radoslaw Sikorski said Friday.

His comment come a day after courts in the Polish capital meted out the first sentences for the street violence, ranging from fines of 115 euros to five months behind bars.

Critics have deemed them too lenient and Sikorki told reporters, “I would like to once again urge Poland’s judiciary to treat these bandits and hooligans with appropriate severity. We don’t need to change the law.”

With Russia facing Greece in Warsaw Saturday, Polish police were gearing up for high alert in a repeat of the unprecedented security operation seen in the capital Tuesday for the drawn game between old foes Poland and Russia.

Amid the worst violence so far at the Euro 2012 football championships, police detained 184 supporters - 157 of them Poles.

Having kicked off June 8 in Warsaw, the 16-nation championships wind up with the final July 1 in Ukraine’s capital Kiev.
