It was yesterday at 21 that two currently unknown perpetrators opened fire against two 15-year-olds at the pizzeria in Malmö. Stefan Sintéus now confirms that both boys were known by the police before.

- They are both born 04 and we know them in criminal contexts even if they are so young, he tells SVT News.

Stefan Sintéus also confirms the information that the shooting was filmed by surveillance cameras.

- There is quite a lot of camera surveillance at Möllevångstorget so there is film. It's something we're looking at now.

Do you have any theories about what is behind the shooting?

- It is clear that we have some ideas and some theories, but there is nothing we can tell about now.
