After a year and a half of investigation, the Rotterdam police lifted eleven Feyenoord hooligans from their beds on Friday morning, not entirely coincidentally, just before the classic, the police let Radio Rijmond know. They are seen as the people behind the Rotterdam Youth Core (RJK). It cannot be ruled out that more arrests will follow. The men are suspected of threats, insults, intimidation and arson, including against Buijsen and Van Dorst.
