Sidney Lute, from Assendelft, has been missing since 2016 and may be in Germany. His mother, Natasja Alderliefste, offered a €10,000 reward for information leading to her son and announced it on the German television programme “Aktenzeichen XY... ungelöst”. Lute was 19 when he left his father’s home at the end of October 2016 without saying where he was going. He later told his mother that he was on holiday and remained in occasional contact with her. On 10 December 2016, he booked a train ticket to Colmar in France, but it is unclear whether he arrived. His digital trail has been missing since Strasbourg. He had taken his laptop, bank card, phone, clothes and identity document.
