FC Utrecht must take into account a penalty for Saturday's disturbances during the home match against RKC Waalwijk.

The professional football prosecutor has decided to start a preliminary investigation.

Referee Richard Martens stopped the game in the Galgenwaard for almost half an hour during the first half, because supporters had repeatedly thrown objects on the field.

Initially, it was about plastic glasses of beer.

Martens sent the players to the dressing room after lighters were also thrown on the field.

"We have to draw the line somewhere," Martens told

ESPN

after a long and noisy evening, which ended in 2-2.

"We did that when lighters were being thrown. Because if we don't do something about it, where will it end?"

Based on the statements of the parties involved, the Prosecutor decided to open a preliminary investigation.

This could result in a penalty for FC Utrecht.

It is not yet clear whether the prosecutor will also investigate Sunday's events at the IJsselderby between Go Ahead Eagles and PEC Zwolle (1-0).

Referee Kevin Blom had to briefly stop the game in Deventer before half time, after supporters had thrown chairs onto the field from the branch.

There were also fireworks.
