Since the report of the disappearance, intensive investigations have been carried out by multiple detective teams. With the deployment of the TGO, these different expertise are brought together, so that the investigation can take place in a more targeted and coordinated manner.
Many tips have already been received, which has also led to the discovery of Tijns suspected bicycle. However, so far there has been no contact with Tijn, and there is no sight of where he may be. At the time he was last seen, he was presumably wearing a black jacket from the brand Moncler and white shoes.
The police are urgently seeking information. Have you seen Tijn after September 12? Or do you know where he might be? Or do you have more information about the disappearance? Then we would like to get in touch with you. This can be done via the tip form or via the investigation tip line at 0800-6070. Prefer to remain anonymous? Then call Crime Anonymous at 0800-7000.
