"Unfortunately, it happens every now and then that you make these kinds of finds in the vicinity of schools and preschools. The fact that drugs are hidden is nothing new. You want to avoid being stopped with this on you and in this case these children ran into hiding," says police spokesman Magnus Jansson Klarin.

It is currently unclear what type of drugs are involved.

"It should be analyzed and weighed," says Magnus Jansson Klarin.

The drugs should not have been in pill form and none of the children consumed any drugs.
