Anti-police riots in Sweden

On the 14th of April the Swedish police was subject to stonethrowing in the southern city of Malmö (third largest in Sweden). A large gang attacked the police what were filing a police report regarding a man with a sword. The gang, mostly younger people, then started the stonethrowing. At a time, the police backed off (sic!) to "calm down the situation" but, of course, that did not work.
The gang soon got reinforced by more people, and around 20:30 they were around 15 persons in the lower teens. Stones, eggs and glasbottles were thrown against the police. A storage was set in fire and when the firedepartment got to the scene, they too were attacked with stones. Quote from the fire department:
"Because of this [the stonethrowing, edit.] and due to the current violence and disturbances in the area the rescue service will wait for police backup before we enter the area…"
At 23:00 there was two storage facilities that was burning. The fire department went near the scene, waited for a large police force and then put the fire out. Again, the stonethrowing started. No one was hurt, and no arrests were made.
