Six people were arrested because of a disturbance in the Johan Cruiff Arena in Amsterdam on Saturday night, during a match between Ajax and Heracles Almelo. The police are investigating whether this incident in the stands is connected with a steward having a heart attack in the stadium, Het Parool reports.
The suspects, five men and a woman, were arrested in and outside the stadium. The investigation is still in full swing, the police said on Sunday. Officers are talking to witnesses and viewing surveillance camera footage.
