The situation was threatening with the police's response force in the school yard while the students were not allowed to leave the school. Julia Dahlén had a biology lesson and saw how a lot of armed police were moving outside the windows.

- I thought it was very uncomfortable, you didn't know what had happened, she says.

- Some students had found out what had happened before the teachers knew, explains Julia Löwengren.

The school staff acted

When the school staff realized the seriousness, they acted quickly and made sure that the students stayed inside the school.

- They locked all doors and asked teachers at every exit and then they put us in the hall and we had to wait, says Emma Eriksson.

"A few cries"

Other students who contact SVT's reporter outside the school talk about how the fear spread among the barricaded students inside the school, some called their parents and some cried.
