Three people in Norrkoping needed medical attention after being hit by police bullets during clashes between police and protesters after the Quran burnings that caused riots in several Swedish towns over the Easter weekend.
Counter-protesters attacked police in some places ahead of planned right-wing extremist demonstrations. Prime Minister Magdalena Andersson has condemned the violence.
Three people seem to have been hit by ricochets and are now being cared for in the hospital. All three of the injured were arrested on suspicion of crime, police said in an online statement, adding none of the injuries were life-threatening.
On Sunday night, the situation in Norrkoping was calm.
Several police and protesters have been injured and multiple vehicles have been torched during the past few days, which has led to a lot of violence.
The violence began on Thursday after a demonstration organized by Rasmus Paludan, leader of the Danish far-right political party Hard Line.
Paludan, who had permission to hold a series of demonstrations across Sweden over the Easter weekend, is known for the burning of Qurans.
