- We learn from it, these are things we have done very well, but there are also things that we need to improve, says Johanna Gunnarsson, security developer at Växjö Municipality.

It was Friday that the alarm went off that a masked person with a knife was seen in the corridors at Teknikum in Växjö. Pupils at the school were locked in classrooms, while the front doors were kept open should anyone need to escape.

Did not know

This was according to plan, but there were also things that worked less well. Among other things, students at Teknikum felt that they did not know what was happening outside the locked classrooms.

In addition, a principal at another school sent incorrect information to relatives. It said there was news that students at Teknikum had been cut, which was not true.

- Information for students and other citizens is something we can be better at, says Johanna Gunnarsson.
