"The classification is 'causing the death of another person,' Chief Prosecutor Joakim Zander tells Corren.
The accident occurred while the police were practicing on the school grounds. A man who was participating as a so-called figurant was hit by a distraction grenade and died.
Joakim Zander declined to say what roles the three people who have now been notified of suspicion had during the exercise, or how they view the suspicions.
In parallel, the investigation into work-environment violations continues, but no suspicions have been raised.
