Right-wing extremist party Tight course leader Rasmus Paludan writes on Facebook that the party will be in Linköping Norrköping on Sunday.
During the Easter weekend starting on Maundy Thursday, protests against Paludan's Koran burning have led to violence in several Swedish cities.
In Örebro, several people were injured and police cars were set on fire.
- We did not know about this and do not know what weight that message has.
We have no confirmed information that he is on his way to our area, says Johnny Gustavsson, press spokesperson at the police region East.
If Paludan carries out the manifestations, then they are not allowed, no permission has been sought or given for them.
- Then we will respond to it in the correct way, we stand for law and order in society.
Exactly how our tactical resources will be distributed, we keep to ourselves for safety reasons, says Johnny Gustavsson.
During Maundy Thursday, rescue personnel and police were attacked at the gatherings in Östergötland and police vehicles were set on fire.
In Linköping, seven people were arrested and in Norrköping at least two, all suspected of violent riots.
Criticism of the police
Over the weekend, several leading politicians have condemned the violence that has broken out and there has also been criticism that the police have given Paludan permission for the rallies.
If the police make the assessment that a socially dangerous situation will arise, they have the right to refuse a permit, criminology professor Jerzy Sarnecki told SVT Nyheter on Saturday.
- In these cases, there were strong indications of it.
Partly because of the national and international situation, partly because there are two parties where one wants to provoke and the other wants to be provoked.
Today, there are strong forces that are hostile to our democracy and that want to create that kind of chaos.
