-When we arrived, the quarrel was overplayed and the patrols noticed that there were some traces of blood, but no one there wanted to tell what had happened, says Carina Andersson, officer on duty at the Stockholm Police.

A moment later, the police received a call from a hospital that a person had sought care for a stab wound.

-It is considered a serious stab wound in the lumbar spine, says Carina Andersson.

The police classify the crime as extremely serious assault and have cordoned off outside the restaurant to carry out a technical investigation.

No suspect has been arrested.
