Police arrested a minor from Hoorn after finding heavy fireworks in a parked car on the Wijzendijkje in Westwoud. Officers had responded to a report that several people were setting off heavy fireworks; the group fled when they arrived, but some later returned and got into the car.

A search of the car found 200 nitrates and 12 cobras, which police confiscated. The boy was released but remains a suspect, and police do not rule out further arrests.
