The temporary pandemic law allows a maximum of eight people to gather at public gatherings such as demonstrations.
The organizer chose not to apply for permission for the demonstration and has now reported for violations of the law.
A total of 50 people were removed with the support of the covid-19 law.
One person has been arrested on suspicion of blue light sabotage and the police have also drawn up a report of a violent riot.
- What we have seen today take place in Stockholm is a demonstration that lacks a permit and leads to a riot where several police officers have been injured.
Where protesters, despite repeated calls, refuse to dissolve it and the gathering is held in violation of regulations aimed at limiting the spread of Covid-19.
It is of course remarkably bad judgment and completely unacceptable, says Mats Löfving, regional police chief in Stockholm in a press release.
"Several attempts at dialogue"
The demonstration started at 14.00 but it took until 17.00 before the police had managed to disperse the crowd.
- Today we had to dissolve a meeting.
This after we made several attempts to have a dialogue with both the organizer and the participants, which did not give the desired result, says Anna Nilsson, commander of the police effort.
National Police Chief "Will never be accepted"
Six police officers were injured during the operation.
- Violence against police employees will never be accepted, says National Police Chief Anders Thornberg.
My thoughts go to our employees who are injured.
