PRAGUE -- An official says 15 fans of Russian club CSKA Moscow have been arrested in Prague for giving a Nazi salute and attacking police.
CSKA lost to Viktoria Plzen 2-1 on Tuesday in their last group match in the Champions League to finish last in Group D.
Plzen is located about 60 miles southwest of Prague.
Police spokesman Jan Danek says the incident took place early Thursday. Danek says one of the fans allegedly gave a Nazi salute while others attacked police, injuring two officers.
Danek says the fans face up to five years in prison if tried and convicted of promoting Nazism and attacking police officers.
The incident is the latest high-profile problem for Russian football as the nation preparwes to host the 2014 winter Olympics and the 2018 World Cup.
In October, UEFA ordered a partial closure of CSKA's stadium after finding their supporters had racially abused Manchester City midfielder Yaya Toure, while later that month Spartak Moscow fans were seen unfurling a banner bearing a swastika during a Russian league match.
