The Ruinerwold Incident refers to a case in the Netherlands where a family was discovered living in isolation on a farm in the village of Ruinerwold. In October 2019, police found a 25-year-old man who had escaped from the property and reported that he and his siblings had been kept in seclusion by their father for years. Authorities later discovered that the family had been living in a hidden basement, cut off from the outside world. The father was arrested, and the incident raised concerns about mental health, control, and the impact of extreme isolation on individuals, particularly children.
