Five people were injured after an attack inside the Assago (Milan) shopping center by a 46-year-old Italian man who, according to reports from the carabinieri, was arrested.
They would all have been hit by a stabbing weapon.
Three of the five injured are in serious condition, so much so that they have requested the intervention of the helicopter rescue.
Three auto-medics, six ambulances and the police were also on site.
The military is rebuilding the dynamic.
At the moment, it is not clear whether it was a quarrel or the gesture of a deranged person.
