Croatian police have launched a probe of some 300 Dinamo Zagreb fans who were removed from the club's stadium for racist chanting during a Champions League qualifier, officials said Wednesday.
The move comes a day after UEFA fined Croatia's champions 25,000 euros ($33,000) and ordered them to close the east section of the stadium for next Tuesday's third qualifying round match against Moldova's FC Sheriff, following racist chanting at a previous match.
UEFA action was brought after the club broke new laws on racism and discriminatory conduct during their 1-0 win over Luxembourg's Fola Esch in the previous round.
On Tuesday, police had to empty a part of the northern section of the Maksimir stadium due to "illegal behaviour of the group of fans despite repeated warnings by the announcer," a police statement said.
Police took personal data and photos from some 300 fans, detaining 67 of them, mostly for lacking identification documents, the statement said.
A criminal probe was launched to establish their possible responsiblity, the statement added.
Local media reported that Dinamo Zagreb hardcore fans, known as Bad Blue Boys (BBB), were chanting insulting slogans against the club's executive president Zdravko Mamic.
Media reports say they were chanting "Mamic you Gypsy, Leave the (Dinamo Zagreb) Shrine."
The same chanting is reported to have prompted UEFA to fine the club that eventually won Tuesday's first-leg match against Sheriff 1-0.
The BBB are known for their hooligan behaviour and were subject to travel bans in the past.
