-We take a big holistic approach to the problem and gather strength against the spiral of violence. We will prosecute, and create security for those who live and work in the area, says Anders Bryngelsson to Aftonbladet.

The effort will, among other things, mean that the police can bring in an extra number of police officers. The hope is that the operation "Portia" will find culprits for unsolved violent crimes but also stop new acts in gang conflicts.

- This means that we can better lead and distribute our resources. The operation is led within the framework of a local special event, says Anders Bryngelsson, press spokesperson at the Stockholm Police.
