The number of schoolchildren carrying weapons rose 20% in the first three months of the current school year, says the Telegraaf.

The figure comes from the latest survey by IRIS, the databank that registers criminal incidents at schools, and translates into 252 weapons over a whole year.
However IRIS says the real number is closer to 1,400 because teenagers only report incidents involving weapons in about 15% of cases.
The possession of weapons and fights are more common at the higher level VWO and HAVO schools than vocational and technical colleges where more theft is reported, says IRIS.
The police are only notified by 28% of schools that find weapons on pupils and only one third of thefts are reported.
