During Tuesday, a large exercise against deadly ongoing violence took place in Norrköping.

Several authorities were involved and the aim was to get better at cooperating in similar events.

- Exercises like this are extremely important, says Mattias Braun, operations leader at the rescue service.

In total, around 100 people took part in the made-up exercise – and this time it ended well.

The police managed to arrest one of the perpetrators and neutralize the others.
