Wednesday's free concert that featured R&b star Akon, took a turn for the bad after police struggled to maintain order with upset fans. Reuters is reporting that violence started after a fire alarrm was pulled out during the show at the Fields Shopping Mall in Copenhagen. 2-3 thousand people attended the event where the director Jens Geppel said "It was a free concert and we knew that many people would come, but there were a lot of people there, more than we had expected." The fire alarm ended up being false, but fans were evacuated and began to protest. At that point officers fought several dozen fans who threw bottles and rocks at them after they were evacuated. Eight people were arrested and emergency services had to treat a number of people who were injured, although no serious injuries were reported.
