The police confirm that the film, which was spread on social media, shows the bombing in Rosengård on Friday night.

- We have not been able to see that it could have damaged our investigation that this film clip has come out, says Nils Norling, press spokesperson at Malmö Police.

Three serious violent crimes

The clipped film shows a man placing a bomb, lighting a stub and running from the scene.

According to the digital watch from the surveillance camera, it took one minute and 42 seconds before the bomb exploded

- In between, you have no control over who could walk by, go out with the dog, go out in the stairwell or whatever.

It is so incredibly ruthless so I can barely speak for it, says Nils Norling.

Bombing can be revenge

During 30 hours, three violent crimes took place in Malmö.

It started on Thursday afternoon when a car was shot at from another car in Bunkeflo.

Two men were arrested within an hour and later arrested on suspicion of attempted murder.

On Friday, two bombs were placed at different addresses in Malmö, which may be revenge actions for the shooting.

The first bomb in Limhamn did not detonate.

However, there was a powerful explosion in Rosengård on Friday night.

There are personal connections between all three violent crimes.

- I do not want to comment on any possible connections between the three different cases.

On the other hand, it is the practice that when it happens, this type of serious violent crime, we always look at possible connections.
