Even before the Danish politician arrived at the scene, there was unrest among the counter-protesters.
Tiles were thrown at the police, and rockets were fired near the park.
On Friday afternoon, the police announced that they had changed the location of the demonstration, which is now being held in central Örebro.
- We have decided to change the location to Sveaparken, says Diana Qudhaib, spokesperson for the police in the Bergslagen Region.
Rasmus Paludan leads the Danish party Tight course.
He has made himself known for provoking, by burning the Koran and showing pictures of the Prophet Muhammad.
In several places in the country, it has become chaotic in connection with the planned demonstrations.
In Rinkeby in Stockholm, several people were arrested on Friday afternoon and during Thursday a violent riot broke out in Linköping, where three police officers were injured.
Even in Norrköping, it was uneasy on Thursday night.
Earlier on Friday, the Örebro police announced that they hoped that the general meeting could be carried out in a safe manner, despite the previous events.
- Of course we have a dialogue with other regions about previous experiences.
At present, the decision remains, says Christina Hallin, press communicator at the police in the Bergslagen region.
