When the Danish right-wing extremist Rasmus Paludan was to burn the Koran in Örebro, the counter-demonstration degenerated into violent riots.
A dozen police officers were injured and four police cars were burned.
Compiles material
The police classify the incident in Sveaparken as a violent riot and are still compiling material from the incident.
According to Torbjörn Roos, they made occasional arrests for disorderly conduct, but were before the riots started.
- We are in an investigation phase in the case.
There is a lot of material sent to us, he says.
Riots in several places
There have been riots in several parts of the country where Rasmus Paludan and his party Tight Course have held demonstrations.
In Norrköping and Linköping, a total of 26 people were arrested on Monday morning for the Easter weekend riots.
