The police response force has been at a number of addresses in southern Stockholm during the evening, but the police are sorry about what the operation is about.

"It is an investigation case that we are doing, so much more I can not say in that case," says Fredrik Andersson, officer in charge of the Stockholm police region. 

Why do you have extra heavily armed police at the scene?

- It probably depends on the danger of the people to arrest.

What can you say about the arrests?

- Nothing.

Ambulances on site

There must also have been several ambulances on site at the operation, but why medical personnel have been called in, the police also do not want to go in.

- Sometimes in our efforts we have health care professionals with whom we work.

Police say on their website that on Sunday, two people were arrested for attempted murder after a man was found with serious gunshot injuries in Liseberg in southern Stockholm yesterday, but if the evening's efforts have links to the incident on Saturday, the police do not want to comment. The two arrested are also suspected of serious weapons offenses.
