Josefin Hedstrand had a children's party on Saturday night.

The night after the party, she woke up to blue lights shining in the apartment.

The reason was the quarrel that took place at the scene a while earlier, where a dozen people rumored together, and where a 25-year-old man was injured so seriously that he died.

- It is a bit worrying considering that we have small children and that it happens so close, says mother of two Josefin Hedstrand.

In the video above, you can hear her tell about the incident where the police tried in vain to save the life of the 25-year-old man.

On Monday afternoon, four men between the ages of 18 and 25 were arrested.

Three people are suspected of murder and one of aiding and abetting murder.
