Trouble broke out when members of the Hells Angels support group AK81 and immigrant youths arrived at the courthouse on Nytorv in Copenhagen.

�Caf� tables and chairs were thrown but no-one was seriously injured and we have not arrested anyone,� the Duty Police Officer tells Ritzau.Friends of those on trial also threatened journalists sent to cover the trial, but a police operation prevented the situation developing.According to an eyewitness, a group of some eight young immigrant youths were waiting in front of the courthouse when five aggressive and vociferous bikers rounded the corner.�The biker-types went straight onto the attack at the group in front of the courthouse with a baseball bat, chairs and tables � but the youths counterattacked,� Ritzau quotes the witness as saying.After a short battle, both groups are reported to have run off.Inside the courthouse, the first major case in the Copenhagen gang war had come to trial.Two young gang members are accused of shooting at a Hells Angels-related clothing and tattooist business in N�rrebro last September. The young men shot through the window of the shop from a scooter, grazing the manager�s neck.
