Naples, March 19 - Family members of a boy who choked to death Tuesday in a kindergarten in Naples laid siege to the school after the boy was pronounced dead at a local hospital. A small group of relatives of four-year-old Patrizio, who died of suffocation from a piece of mozzarella, entered the Sabatino Minucci kindergarten and elementary school, threatening teachers. Patrizio was taken to the Cardarelli hospital less than one kilometer away when his teacher realized that the boy was choking in the school cafeteria. The husband and wife owners of a pizzeria across the street from the school rushed the boy to the hospital when they heard the teacher cry for help. Doctors removed an olive-sized piece of cheese that was blocking the boy's air passage, but he was pronounced dead on arrival. "It is unthinkable that in a school where there is a cafeteria that not one person was able to cope with the situation. Across the street there is a pharmacy and further down the road a clinic," said one student's mother.
