Luleå's hockey fans broke the ban with flags in the stands and the SHL club is therefore reported to the Swedish Ice Hockey Association's competition committee.
In the autumn, Luleå, like several other clubs, was penalized after fans lit pyrotechnics of some kind in the stands. The penalty was a ban on supporter items at home games, i.e. a ban on flags.
In Luleå's home game against Linköping on Saturday, the fans defied the flag ban, which has now been reported to the competition committee.
The penalty can be anything from a fine or a fine to playing without an audience.
