Police have arrested two people in connection with the sabotage on the railway during Prinsjesdag, the public prosecution service (OM) announced on Friday. A 49-year-old man and a 41-year-old woman from Drenthe were arrested on Thursday. According to the OM, the pair remain suspects but there was not enough evidence to keep them in custody. Train services across the country were disrupted in September in what network operators described an act of coordinated sabotage.
