At a pre-trial hearing, with limited access for the media at the Lelystad courthouse, northeast of Amsterdam, the teenagers and a 51-year-old man whose 16-year-old son was with him in the dock, were all charged with the death of Richard Nieuwenhuizen on December 3.

Nieuwenhuizen, 41, died a day after being allegedly kicked several times in the head during an attack by enraged young opposition footballers shortly after the final whistle of an amateur game.
