The unrest began shortly after 10pm in Husby, northwestern Stockholm where the riots began on Sunday night. Youths gathered in the town square, some of them masked.

Hagsätra in southern Stockholm came under fire at roughly the same time. A police patrol was attacked, and one officer was taken to hospital with serious injuries to the head.
By 2am, Stockholm’s fire service had attended 75-80 incidents across the city. Much of their work was delayed by youths throwing stones at them, meaning police were left to attend to the stone-throwers to allow the fire fighters access to the fires.
A restaurant went up in flames in Skogås, southern Stockholm. Police labelled the crime as aggravated arson.

In Rågsved, a police station was set on fire, with officers gathering young people in a police bus and escorting them away to other parts of the city.
Local residents in Husby claim the town is usually quiet and calm, with many strongly critical of the young people responsible for the crimes.
Many believe the catalyst to the riots was the fatal police shooting of a machete-wielding 69-year-old man in the area last Monday.
